Arizona State University has placed head hockey coach Greg Powers on administrative leave while the school investigates the collapse of defenseman Matthew Mayich during an outdoor workout on August 20.
Mayich, 21, suffered an external heat stroke that reduced oxygen flow to his brain, according to a family attorney. He is unlikely to recover. Powers will not coach the season opener against Lindenwood, and assistant Mike Corbett will lead the team.
Seven players sent an anonymous letter to President Michael Crow on Monday, urging the university to place the coaching staff on leave pending an independent investigation. They cited failures to follow the school’s exertional heat policy, including lack of progressive acclimatization, insufficient rest periods, and limited fluid access during the 75‑minute workout.
Mayich’s parents, John and Christina, agreed with the players that the coaches should be placed on leave. The National Collegiate Hockey Conference also supported the decision, expressing concern for the player, his family and teammates.
ASU athletic director Graham Rossini said the focus remains on Matthew and his family and on providing support to student‑athletes. An interim coach will be named soon, and the university continues to gather information to ensure stability for the program.
