A 21‑year‑old defenseman for Arizona State University’s hockey team, Matthew Mayich, was hospitalized after collapsing during an outdoor training session on the first day of the fall semester.
The Training Session
The workout was led by retired U.S. Army Special Forces veteran Tim Zeisel, who volunteered to train players at a nearby Christian university. Temperatures that day hovered between 87 and 89 degrees Fahrenheit. Zeisel departed the session before Mayich fell, after which the exercises continued with activities such as running while carrying medicine balls.
Medical Response and Hospitalization
Tempe firefighters responded to a heat‑related illness call and provided immediate care before transporting Mayich to a local hospital. He was subsequently transferred to the Barrow Neurological Institute, where he has remained in a coma for more than ten days.
University’s Investigation
Arizona State University officials have opened a formal review of the incident, citing concerns over the conduct of the training session and the role of the external trainer. While the university has not disclosed details of the workout plan, it has pledged a thorough examination of safety protocols.
Community Support
The episode has galvanized a wave of solidarity on campus and beyond. Former teammates, friends and community members have organized daily prayer services and posted messages of encouragement, while Mayich’s family has expressed gratitude for the outpouring of support.
Implications for Campus Athletics
The case raises broader questions about the oversight of off‑season conditioning programs and the responsibilities of private trainers working with college athletes. As the investigation proceeds, the incident underscores the risks associated with high‑intensity exercise in extreme heat.
Authorities continue to gather information, and the university expects to release findings once the review is complete.
