Arizona State University has appointed Dave Hakstol as the new head coach of its men’s hockey program amid an ongoing investigation into a serious player injury sustained during an outdoor workout. The announcement comes after the previous coach, Greg Powers, resigned following the collapse of 21-year-old forward Matthew Mayich, who is currently on life support due to heat stroke.

The incident occurred during a recent outdoor training session, where Mayich suffered from external heat stroke—a condition that has left him with critical injuries and a poor prognosis for recovery. In response to the event, Arizona State initiated a formal inquiry into the circumstances surrounding the workout and the team’s safety protocols.

Hakstol, 58, joins Arizona State with extensive coaching experience at the collegiate and professional levels. He served as head coach at the University of North Dakota for 11 seasons, guiding the program to seven appearances in the NCAA Frozen Four tournament. Hakstol also has NHL coaching experience, including stints with the Philadelphia Flyers and Seattle Kraken, and most recently served as an assistant coach with the Colorado Avalanche.

The university has not released specific details regarding the ongoing investigation but has emphasized the priority of player safety and well-being. Greg Powers’ decision to step down came as the organization seeks to address concerns raised by the incident and to begin a new chapter under Hakstol’s leadership.

Arizona State’s hockey program has gained recognition in recent years for its rapid development and competitive presence in college hockey. The appointment of Hakstol is expected to bring experience and stability to the team as it navigates the aftermath of the tragic injury and related scrutiny.

Further updates regarding the investigation and Mayich’s condition are expected as the university continues its review and the hockey program moves forward.
