Story summary

Seven members of Arizona State’s hockey team anonymously sent a letter through attorney Timothy J. Casey to President Michael Crow on Monday, calling for the coaching staff to be placed on administrative leave until an independent investigation is completed into the collapse of their teammate Matthew Mayich during an outdoor workout on Aug. 20. The players fear retaliation from head coach Greg Powers and his assistant coaches, who control playing time, scholarship levels, and roster status. The letter disputes ASU’s initial probe, which stated that Mayich received proper hydration and care after collapsing; the players assert he did not receive adequate medical attention or hydration during the workout.

The parents of Matthew Mayich, John and Christina Mayich, also called for coaches involved to be placed on leave in a statement sent through their lawyer. In response, ASU athletic director Graham Rossini announced that head coach Greg Powers has been put on paid administrative leave pending an independent investigation into the incident.

NCHC supports this decision, stating it aligns with providing stability and support for both Matthew Mayich and the hockey program during these challenging times.
