Arizona State Hockey Coach Refuses to Explain Workout That Left Player Matthew Mayich With Little Hope of Recovery

An Arizona State University hockey player remains hospitalized after collapsing during a strenuous outdoor workout, while questions about the training session and the response to his medical emergency continue to raise concern.

Matthew Mayich, 21, suffered a medical crisis during a team workout on August 20, 2026. According to reporting by PEOPLE, an attorney representing his family said Mayich experienced exertional heat stroke that deprived his brain of oxygen, leaving him with virtually no chance of recovery.

The workout was reportedly led by Tim Ziesel, a former Green Beret who was conducting a military-style training session for the team. Reports cited by The Athletic said Mayich began stumbling and struggled before collapsing. Teammates and staff eventually recognized that he was in serious distress.

The circumstances surrounding the incident have prompted questions about the intensity of the workout, access to water, and how quickly medical assistance was provided. Some players reportedly raised concerns about the response after Mayich collapsed, while the university has faced calls for greater transparency.

Head coach Greg Powers addressed reporters in September but declined to answer questions about the August 20 workout. When asked about his responsibility for what happened, he said he could not discuss the incident. His refusal to comment publicly drew criticism as the investigation continued.

Mayich’s family has been left facing an agonizing situation. His parents have described their son as a fighter and said he had been ready for the upcoming hockey season before the workout. They continue to seek answers about the circumstances that led to his hospitalization.

Arizona State University has launched a review of the incident, including questions about the planning and supervision of outdoor athletic activities and the policies designed to protect student-athletes. The university has not publicly resolved all the questions surrounding the workout.

The case has also renewed debate about athlete safety, particularly when demanding training sessions take place in hot weather. Medical emergencies such as exertional heat stroke can become life-threatening quickly, making early recognition and rapid treatment critical.

As the investigation continues, Mayich’s family and teammates are seeking clarity about what happened that morning and whether different decisions could have changed the outcome.
