St. Louis Blues prospect Matthew Mayich remains hospitalized following a medical emergency during an outdoor workout at Arizona State University on August 20. Attorney Rob Carey stated that the 21-year-old athlete suffered an exertional heat stroke that caused a lack of oxygen to the brain. According to reports, the athlete became disoriented during a military-style training session conducted in extreme temperatures while under a local heat warning. Counsel for the Mayich family alleged that the athlete received minimal water during the practice, which occurred on his first day with the team.
