Arizona State Hockey Health Crisis Sparks Investigation

An Arizona State University hockey player experienced a sudden collapse during practice last Thursday morning and was swiftly transported to the hospital, as reported by The Athletic this past Tuesday.

Identified as 21-year-old Matthew Mayich, he remained under medical care as of Tuesday, according to someone familiar with the family’s situation who confirmed this to the news outlet.

Chris Fiscus, who serves as the Vice President of ASU media relations, communicated that an ongoing investigation is being conducted into the “circumstances surrounding the workout.” Mayich’s name has not yet been officially released by the university.

“The university extends its support to the student-athlete, his family, and all student-athletes during this challenging period,” a spokesperson from Arizona State communicated to the Arizona Republic.

Responding to a call about a “heat-related illness,” Tempe Fire Medical Rescue dispatched a team at 8:31 a.m. to 400 S. Rural Road, the location of Sun Angel Stadium, an outdoor track and field venue.

A patient was treated at the site and then transported to a local hospital.

Phoenix has been in an extreme heat warning all week and the average temperature Thursday was 92.5 degrees with a high of 106 degrees in the afternoon.

Fiscus declined to answer whether the workout was team sanctioned.

NCAA rules enable college hockey teams to begin formal activities when classes start, and ASU kicked off its fall semester Thursday.

Mayich, who is a sophomore defenseman, started his college career at Clarkson before transferring to Arizona State this offseason.

The St. Louis Blues selection him in the sixth round of the 2023 NHL Draft.

Last season with Clarkson, he scored 15 points on seven goals and eight assists.

Mayich also previously played in the Ontario Hockey League for over 250 games.
