Matthew Mayich, a 21-year-old NHL prospect from Hamilton, was hospitalized after collapsing during a training session at Arizona State University (ASU) on August 20. His family lawyer, Rob Carey, claims that Mayich suffered exertional heatstroke and underwent a "brutal" workout with no breaks or water for over an hour, which he believes contributed to the collapse. The university is conducting an investigation into the incident, led by senior vice-president James Rund, but has been criticized by Carey for being "tight-lipped" about what occurred. According to the BMJ Medicine journal, exertional heatstroke has a mortality rate of around 27% and long-term negative health consequences for survivors.
