Arizona State University hockey player Matthew Mayich remains in a coma following a medical emergency during an outdoor workout on August 20. The 21-year-old athlete collapsed at the Joe Selleh Track during a training session led by an external instructor. Attorneys for the family allege the university failed to follow established heat safety protocols, noting Mayich had arrived in the area less than a week prior to the session. School guidelines require a seven to 14-day acclimatization period for athletes before engaging in high-intensity training during extreme heat. Reports indicate the athlete was not immediately placed in a cooling station or ice bath after collapsing. ASU officials have acknowledged the existence of heat policies but have not confirmed whether they were followed during this specific workout.
