NHL hopeful Matthew Mayich remains in critical condition following a troubling training incident that occurred on August 20. The 21-year-old was participating in a military-style workout organised by the Arizona State Sun Devils when he collapsed, prompting a series of alarming revelations from eyewitness reports.

According to a detailed report published by The Athletic, Mayich’s physical distress became apparent during a bear crawl exercise. Eyewitnesses alleged that he appeared disoriented and struggled to maintain his footing multiple times before ultimately collapsing. Near the end of the session, he dropped a medicine ball mid-race and was unable to rise after repeated attempts. His teammates and an assistant coach were quick to call for help, but by the time they reached him, Mayich was reportedly lying on the ground, incoherent and in a state of distress.

The workout was led by Tim Ziesel, a former Green Beret enlisted to guide the hockey team’s first day of organised practice. Ziesel, believed to have a hand-shake agreement with head coach Greg Powers, instructed the players through a series of physical challenges, including squats and push-ups, at the unshaded Sun Angel Stadium, where temperatures were soaring. Witnesses indicated that the workout had become particularly intense, with some players even succumbing to nausea.
Reports suggest that Ziesel created a daunting atmosphere, allegedly belittling players during the session. After he concluded the exercises by assigning a relay race, he departed the field, leaving the team to complete the final challenge without his guidance. As the last few players, including Mayich, commenced the relay, conditions appeared dire.
In the wake of Mayich’s collapse, he reportedly lay in the sun for several minutes before being assisted by four teammates, who carried him into the shade. An athletic trainer quickly provided water and an ice pack for his chest, but significant time lapsed before emergency services arrived, approximately an hour and a half post-workout.
Mayich’s family has since revealed that he has been diagnosed with exertional heat stroke, resulting in a critical lack of oxygen to the brain. Rob Carey, the attorney representing the Mayich family, mentioned in an interview that “there were no other contributing conditions”; they are solely facing the dire consequences of heat exertion. Additionally, Carey expressed the gravity of the situation, saying the young athlete now has “zero chance of recovery.”
This tragic incident has sparked discussions about the responsibility of coaching staff and the safety protocols in place during such demanding training sessions. The National Hockey League (NHL) and college sports organisations are increasingly under scrutiny for ensuring the safety and well-being of athletes, particularly in high-temperature conditions, where the risk of heat-related illnesses is paramount.
As the situation unfolds, there has been a noticeable absence of comments from Tim Ziesel and his legal representation. This lack of communication raises questions about accountability and the measures that will be taken moving forward to prevent future incidents of this nature in collegiate athletics.
The heart-wrenching situation serves as a stark reminder of the potential dangers athletes face during intense training drills, and it has heightened awareness about the rigorous demands placed on young athletes striving for professional prowess. With the Mayich family calling for a miracle, the hope is that this incident encourages urgent reforms in training protocols, aiming to safeguard the health of student-athletes everywhere.
