Key Highlights

• Seven Arizona State hockey players, through an attorney, sent a 26-page anonymous letter to ASU President Michael Crow asking that head coach Greg Powers and his assistants be placed on administrative leave after a grueling Aug. 20 workout left sophomore Matthew Mayich incapacitated and later on life support.
• Players allege inadequate hydration, poor medical monitoring, and an insufficient emergency response during a 75-minute outdoor session run by an ex–U.S. Army Green Beret; those accounts directly contradict parts of the university’s initial review, which itself found problems with hydration and medical care.
• The case raises larger questions about heat-illness protocols, the role of nontraditional trainers in collegiate programs, athletes’ ability to report safety concerns without fear of retaliation, and what an independent investigation must examine to restore trust.

Introduction

A routine preseason conditioning session became the focal point of a campus controversy and a demand for accountability. On Aug. 20, an Arizona State University hockey workout left a sophomore player incapacitated, later placed on life support. In response, seven teammates—anonymous for fear of retaliation—deliver a stark claim: the session was mismanaged, the player was not properly monitored or cooled, and the response after collapse fell short of accepted medical practice.

Their 26-page letter to university leadership seeks immediate action: place head coach Greg Powers and his assistant coaches on administrative leave while an independent investigation proceeds. The letter challenges the university’s initial review of the incident, supplies a detailed account of what happened on the field that afternoon, and sheds light on how team dynamics and power structures can deter players from speaking up about safety. The university’s review acknowledged deficiencies in hydration and medical care, yet players say key facts in that report are wrong. The dispute centers on a few critical questions: what actually happened that day, did staff meet the required standard of care, and how will the university respond when emergency medical judgment and athletic performance incentives collide?

This article reconstructs the accounts reported by teammates, summarizes the institution’s findings and gaps, explains the medical standard for exertional heat illness and rapid cooling, explores legal and ethical dimensions, and outlines what a thorough investigation should look like. The goal is to present a clear, evidence-based picture of the incident and the systemic issues it has exposed.

The Aug. 20 Workout: Teammates’ Timeline and Allegations

According to the 26-page letter sent by seven Sun Devils through counsel, the workout on Aug. 20 was run outdoors, lasted roughly 75 minutes, and was described by players as "grueling." An ex–U.S. Army Green Beret led the session. The letter paints a sequence of events that places the team and the coaching staff under scrutiny.

Key elements of the players’ account:

• The session included high-intensity drills such as bear crawls and buddy carries. Players reported that Mayich displayed signs of distress early on, becoming disoriented during the bear crawl and being unable to perform the buddy carry.
• The only water break occurred late in the session, the players say. They dispute the university’s claim that a water break was provided about 20 minutes in; instead, they say the first true opportunity to access water arrived roughly 40 minutes in and lasted only a few seconds. Because of the structure of the drill, only the first eight players to finish the bear crawl had a chance to drink before being ordered back.
• The ex-Green Beret allegedly admitted forgetting that a water break was needed. Teammates said he added that he did not drink water during combat missions, suggesting a mindset unsuited to conditioning athletes in high heat.
• When Mayich collapsed, players say he remained in direct sunlight for several minutes and required carrying into the shade by teammates. They describe limited cooling options—towels from a cooler, water bottles, and a garden hose—insufficient measures given Arizona’s August heat, which routinely exceeds triple digits.
• No one on the staff adequately monitored Mayich during the workout and no one intervened when he showed clear signs of trouble, according to the letter. The players allege the coaching staff and team leadership failed to treat his condition as serious.
• After the collapse, players reported that head coach Greg Powers downplayed the seriousness of Mayich’s condition when speaking with the team, calling it "a little heat stroke." Players say Powers did not appear to grasp the severity of the situation.

The letter emphasizes why the players chose anonymity. They note that the head coach and assistants remained on the field that day, hold influence over playing time, scholarship status, and roster decisions, and that speaking openly could jeopardize their collegiate careers. The letter’s stark line captures this tension: "We should not have to choose between telling the truth about August 20 and keeping what we have worked our whole lives for."

The University’s Initial Review: What It Found — and What Players Dispute

Arizona State conducted an internal review of the incident. That review did identify shortcomings: specifically, that Mayich did not receive proper hydration and that medical care after his collapse was inadequate. Those findings place the university on record acknowledging failings.

Yet the review’s factual account differs from the players’ recollections on crucial points:

• Timing and sufficiency of water breaks. ASU’s review reported a water break about 20 minutes into the session. Teammates say the break occurred significantly later, was only a few seconds long, and only a handful of players actually accessed water.
• Positioning and cooling after the collapse. The university stated that Mayich sat upright twice after collapsing. Players counter that he remained in direct sunlight and required teammates to carry him into the shade.
• Monitoring and intervention. While the review acknowledges inadequate medical care, players assert a broader failure: active lack of monitoring during the workout, no staff intervention when Mayich showed early and escalating signs of distress, and a general underestimation of risk by those supervising.

The players’ letter argues the review does not fully reflect the reality of the workout and fails to hold the staff accountable. They request that Powers and assistants be placed on administrative leave so the investigation can proceed without the influence of those who were directly involved in the session and who retain control over players’ futures.

Exertional Heat Illness: Medical Standards and Immediate Response

The descriptions from teammates align with textbook warning signs for exertional heat illness: disorientation, failure to complete tasks that teammates can complete, and collapse. Medical consensus establishes a clear hierarchy of response when exertional heat stroke is suspected.

Recognizable clinical points and actions:

• Symptoms. Early signs include dizziness, confusion, nausea, profuse sweating followed by an absence of sweat in some cases, weakness, and altered consciousness. An athlete who becomes disoriented or cannot perform previously manageable tasks is at elevated risk.
• Immediate action. Cease activity immediately. Remove the athlete from direct sun and ventilate. Remove excess clothing to facilitate cooling. Rapid cooling is essential; cooling must start without delay while emergency medical help is on the way.
• Cooling method. Ice-water immersion is widely regarded as the most effective and time-tested method to rapidly reduce core temperature in exertional heat stroke cases. If immersion is not immediately available, applying ice packs to major vascular beds, using water dousing, and moving to an air-conditioned environment are alternative measures until definitive cooling can begin.
• Time sensitivity. The rate at which core body temperature is lowered correlates with outcomes. Delays in rapid cooling significantly increase the risk of organ damage, long-term disability, and death.
• Medical monitoring. Continuous monitoring of airway, breathing, circulation, and core temperature is critical. Immediate activation of emergency medical services when exertional heat stroke is suspected is standard practice.

The players’ description—that Mayich remained exposed to direct sunlight, had limited access to cooling measures, and was not adequately monitored—conflicts with these accepted standards of care. If verified, those shortcomings would represent failure to deploy best-practice responses for a heat-related medical emergency.

Military-Style Training in Athletic Settings: When Tactics Don’t Translate

The workout at issue was led by an ex–U.S. Army Green Beret. Military experience brings discipline and endurance training skills, but combat conditioning and sports conditioning differ in purpose, context, and risk calculus.

Differences that matter:

• Objective. Military training emphasizes mission-readiness under austere conditions, sometimes with deliberate stressors mirroring combat. Sports conditioning optimizes performance while preserving short- and long-term athlete health.
• Environment and limits. Military personnel are trained to operate under extreme conditions with acclimatization and mission-driven tolerances. Athletes are not soldiers; their training must respect physiological boundaries, sport-specific recovery timelines, and medical oversight.
• Hydration and recovery protocols. In the field, water may be scarce; training may intentionally limit resources. Athletic training must prioritize hydration, scheduled breaks, and gradual acclimatization to heat.
• Chain of command and risk reporting. Military structures accept hierarchical decision-making that may discourage questioning orders. In collegiate sports, power dynamics can create similar barriers. Coaches control scholarships and playing time, and athletes may fear speaking up.

The letter from ASU players highlights this clash. The purported remark from the trainer—stating he did not drink water during combat missions—reflects an ethos that, if applied unmodified to collegiate athletes in triple-digit heat, can be hazardous. Integrating former military trainers into athletic programs requires clear boundaries and medical oversight, ensuring that tactics used in combat training are adapted to the physiology and safety needs of student-athletes.

Institutional Responsibility: Coaches, Athletic Trainers, and the Duty of Care

Colleges have a duty of care to student-athletes that spans training design, supervision, medical support, and emergency planning. Athletic departments are expected to maintain established emergency action plans, ensure qualified medical personnel are present or available, and empower staff to halt activities when conditions become unsafe.

Components of institutional responsibility:

• Qualified personnel. Certified athletic trainers should be present or immediately available during high-risk conditioning sessions. Those supervising workouts must be trained to recognize heat-illness signs and execute emergency response.
• Emergency action plans (EAPs). Programs should have clear, rehearsed protocols for medical crises that include cooling procedures, communication protocols, and coordination with local emergency medical services.
• Environmental monitoring. High heat and humidity increase risk. Programs should monitor wet-bulb globe temperature (WBGT) or comparable indices and adjust practice intensity and duration accordingly.
• Athlete education and acclimatization. Athletes must be educated on hydration, signs of heat illness, and encouraged to report symptoms. Conditioning programs should allow gradual acclimatization to heat over 7–14 days, especially for athletes coming from cooler climates.
• Reporting protections. Because coaches control playing time and scholarships, athletes must have confidential reporting mechanisms that protect them from retaliation when raising safety concerns.

When any of these components fail, the institution becomes exposed to medical, legal, and reputational consequences. The players’ letter contends several of these safeguards were absent or ignored on Aug. 20.

Legal and Ethical Stakes: What the Players’ Letter Triggers

The involvement of attorneys and the decision by players to seek anonymity elevate this matter from an internal dispute to a potentially litigious and public issue. Legal claims may rest on negligence principles: did ASU staff exercise reasonable care in supervising workouts, providing hydration and cooling, and responding to medical emergencies?

Potential legal considerations:

• Standard of care. In civil litigation, the inquiry often centers on whether staff met the standard of care expected of athletic programs and medical personnel under similar circumstances.
• Documentation and evidence. Training logs, medical incident reports, video footage, environmental readings, and witness statements will be central to any legal or administrative review.
• Institutional liability. Universities have been held accountable when institutional policies were inadequate or when staff failed to follow established protocols.
• Criminal liability. Criminal charges in such cases are uncommon and typically hinge on deliberate or grossly reckless conduct. An independent investigation would need to determine whether actions rise to that threshold.

Ethically, the case raises questions about athlete welfare versus competitive advantage. The players’ letter suggests that coaching decisions—about playing time and scholarships—can suppress truthful reporting about safety. That conflict presents an ethical failure even before legal conclusions are drawn.

The Athlete at the Center: Who Is Matthew Mayich

Matthew Mayich is a sophomore on the Arizona State hockey team and an Ontario native. Before arriving at ASU, he played junior hockey, including time with the Ottawa 67’s. Mayich was selected 170th overall by the St. Louis Blues in the 2023 NHL Draft, a milestone that underscores his standing as a legitimate professional prospect.

Teammates described Mayich as particularly vulnerable to the Arizona heat. They wrote that he spent much of his downtime in air-conditioned housing because the outdoor heat was oppressive for him. That observation provides context for why a prolonged outdoor workout in triple-digit temperatures could present disproportionate risk for him.

Publicly available details on Mayich’s current medical status remain limited in the reporting. The initial accounts indicated he was incapacitated and placed on life support following the collapse in August; further updates from the university, his family, or medical team would clarify his condition and prognosis.

Why Players Chose Anonymity and the Institutional Power Dynamic

The seven players sent their letter anonymously through legal counsel. Their stated reason: fear of retaliation from the coaching staff who control playing time, scholarship renewals, and roster status. They explained that "No one has separate us from them since that morning," capturing how tightly coaches’ authority can influence players’ willingness to speak out.

This dynamic carries implications:

• Silence and underreporting. When athletes fear the immediate economic or career consequences of speaking up, safety issues may go unreported until serious harm occurs.
• Need for independent reporting channels. Universities must provide mechanisms for confidential reporting that do not leave athletes vulnerable to immediate, career-altering reprisals.
• Administrative leave as a safeguard. Players requested that Powers and his assistants be placed on administrative leave to allow an independent investigation to proceed without the perceived pressure their continued presence could exert.

The request for administrative leave is consistent with investigative best practices. When staff implicated in an incident remain in positions that affect witnesses, the perception of bias and the chilling effect on testimony can undermine the integrity of any review.

What a Thorough Investigation Should Examine

An authoritative inquiry should be comprehensive, transparent, and independent. To restore trust and determine accountability, investigators must compile evidence and analyze protocols against accepted medical and athletic standards.

Critical elements of a robust investigation:

• Detailed timeline. Exact times for the start and end of drills, when signs of distress first appeared, timing and duration of water breaks, and the moment of collapse.
• Witness statements. Accounts from teammates, staff, and any bystanders. Anonymity should be an option to protect players from retaliation, while assuring the credibility of statements through corroboration.
• Video and photographic evidence. If available, video footage of the workout and the collapse can resolve disputed facts such as positioning, duration in sun, and staff response.
• Medical records. Pre-workout screenings, any pre-existing medical conditions, records of on-site medical evaluation, transport notes, and hospital records if available.
• Environmental data. Temperature, humidity, and other environmental metrics for the field on Aug. 20. Use of WBGT or analogous measurements is ideal.
• Trainer qualifications and protocols. Credentials of the ex-Green Beret and other staff, their familiarity with sport-specific heat illness management, and whether written protocols were followed.
• Emergency response assessment. Evaluate whether emergency procedures complied with accepted standards, including the use or absence of rapid cooling methods and the timing of EMS activation.
• Prior practices and culture. Examination of prior workouts, whether outdoor sessions were typically brief (players reported prior outdoor workouts lasting around 15 minutes), and whether there is a pattern of pushing athletes beyond safe limits.
• Institutional oversight. Review of how athletic department leadership supervises conditioning programs and the mechanisms by which complaints escalate.

An independent investigation that includes medical and athletic expertise will yield the most credible findings. Transparency about process and findings will be essential to restoring confidence among players, families, and the public.

Prevention: What Programs Should Do to Avoid Heat-Related Emergencies

The incident at ASU, regardless of final findings, illustrates prevention gaps that other programs must heed. Colleges can reduce risk by instituting clear policies, training staff, and ensuring athletes’ protection.

Actionable measures for programs:

• Pre-activity risk assessment. Measure environmental heat indices and adjust or cancel outdoor workouts when risk exceeds safe thresholds.
• Hydration protocols. Schedule frequent, sufficient water breaks and ensure easy access for every participant. Avoid one-size-fits-all breaks that disproportionately disadvantage those later in a drill sequence.
• Acclimatization periods. Build heat exposure gradually, especially for athletes arriving from cooler climates, with progressive increases in intensity and duration over days to weeks.
• Qualified medical coverage. Ensure certified athletic trainers or medical professionals are present or immediately available during high-risk sessions.
• Emergency readiness. Maintain equipment and facilities for rapid cooling, including ice tubs or other effective immersion capabilities when appropriate, and rehearse EAPs regularly.
• Education and empowerment. Teach athletes to recognize symptoms of heat illness and ensure confidential reporting mechanisms if they or teammates feel unsafe.
• Limit military-style approaches. When hiring staff with military backgrounds, require adaptation training to translate combat conditioning methods safely into athletic training contexts.
• Documentation. Maintain records of workouts, attendance, environmental readings, and medical interactions to support transparency and accountability.

These measures are practical and rooted in clinical and athletic best practices. Implementing them reduces the likelihood of an event escalating into a life-threatening emergency.

The Role of Leadership: Athletic Directors and University Presidents

University leadership carries responsibility for the culture and safety of athletic programs. When potential breaches of care occur, rapid, transparent action from athletic directors and university presidents can limit harm and restore confidence.

Leadership actions that matter:

• Commission independent investigations. An outside review by experts in sports medicine and emergency response reduces conflict-of-interest questions.
• Temporary administrative actions. Placing implicated staff on administrative leave during investigation is standard practice to remove potential pressure on witnesses.
• Public communication. Consistent, factual updates protect the university’s credibility while respecting privacy and legal constraints.
• Policy reform. Use findings to update policies on conditioning, trainer qualifications, and athlete protections.
• Support for affected families and athletes. Provide medical, psychological, and logistical support to injured athletes and their families without conditionality.

The players’ appeal to President Michael Crow is an appeal to this very chain of accountability. How university leadership responds will set the tone for how seriously player safety is prioritized.

Broader Reflections: Conditioning Culture, Power Imbalances, and Athlete Safety

This incident touches on a deeper debate in college sports: the balance between rigorous conditioning and the protection of young athletes. Coaching cultures that valorize toughness can sometimes blur into practices that disregard physiological boundaries. Power imbalances—coaches determining scholarships and playing time—create incentives for silence.

Key reflections:

• Toughness versus safety. Athletic cultures should prize resilience, but not at the expense of health. Distinguishing between productive discomfort that builds performance and dangerous stressors is essential.
• Transparency versus preservation. Universities must commit to transparent reviews of incidents involving serious injury. Defensive institutional behavior corrodes trust.
• Empowering athletes. Policies that reduce fear of retaliation enable athletes to report unsafe conditions early, preventing escalation.
• Adapting best practices. Coaches and trainers should align conditioning with sports medicine standards and revise practices when new evidence or local conditions demand it.

This situation is a reminder: systemic change is necessary to prevent a future where competitive goals overshadow basic human safety.

What's Next: Investigation, Season Start, and Monitoring Outcomes

The Sun Devils are scheduled to begin their 2026–27 season against Lindenwood, but the fallout from Aug. 20 will linger. The players’ letter demands administrative leave for the coaching staff and calls for a transparent, independent inquiry. The university’s initial review has already acknowledged failings in hydration and medical care; the players insist the review is incomplete or inaccurate.

Outcomes to watch:

• Whether ASU places Powers and his assistants on administrative leave while an independent investigation is conducted.
• Whether the university commissions outside experts in sports medicine and emergency response to review procedures and the specific incident.
• What corrective measures ASU adopts—policy changes, staff retraining, upgraded medical protocols, or disciplinary action—if investigators find negligence or systemic lapses.
• Medical updates on Mayich’s condition and any support the program provides to him and his family.
• Broader ripples in collegiate athletics regarding military-style trainers and the oversight of conditioning programs.

For athletes, families, and administrators, the critical questions are accountability and prevention. A credible investigation followed by substantive reforms would demonstrate institutional commitment to athlete welfare.

FAQ

Q: What exactly happened to Matthew Mayich on Aug. 20? A: According to a 26-page letter from seven anonymous teammates, Mayich became disoriented during a 75-minute outdoor workout, failed to complete several drills, and ultimately collapsed.
