- A member of Arizona State’s men’s hockey team collapsed during an outdoor exercise and was treated on site before being taken to hospital after the incident on Thursday, Aug. 20.
- The player was identified by team and family sources as 21-year-old Matthew Mayich, a sophomore defenseman and a 2023 St. Louis Blues draft pick.
- Tempe Fire Medical Rescue responded to the Sun Angel Stadium track at about 8:30 a.m. and described the initial call as a heat-related illness.
- Family sources and multiple reports say Mayich suffered a possible cardiac event and was placed in a coma, while the Blues and hockey organizations have issued statements of support and said they are being kept informed through his agent.
- Arizona State says it is reviewing the circumstances of the workout but has not confirmed whether it was a team-sanctioned practice, and coverage notes that extreme-heat warnings that week have focused attention on campus training protocols and institutional transparency.
