Story summary

On August 20, 21-year-old Matthew Mayich, an NHL prospect drafted by the St Louis Blues, collapsed during an early morning outdoor workout at Arizona State University (ASU). He remains in critical condition after suffering from exertional heatstroke, with his family attorney stating he is unlikely to make a meaningful recovery. ASU’s investigation revealed that the hockey coaching staff did not submit their training plan for review before the workout began, despite knowing it would take place outdoors on a day when temperatures reached around 30°C. This incident has raised significant concerns about the lack of proper safety measures and emergency protocols for young athletes during extreme weather conditions. The university is now considering forming an expert panel to develop better practices for planning and responding to adverse events in outdoor athletic activities.
