St. Louis Blues prospect Matthew Mayich remains hospitalized after collapsing during a workout that Arizona State University is now investigating.

Last Thursday, St. Louis Blues prospect Matthew Mayich collapsed after a workout.

Arizona State University is investigating a workout that led to Mayich's collapse and subsequent hospitalization, according to a report from The Athletic's Kate Strand and Jeremy Rutherford on Tuesday.

“A student-athlete who collapsed during an outdoor exercise Thursday morning remains hospitalized,” ASU vice president of media relations Chris Fiscus told The Athletic. “The student-athlete, a member of the ASU hockey team, is not being named by the university because of privacy interests. The university is reviewing the circumstances surrounding the workout.”

Fiscus did not say whether the workout was sanctioned by the ASU hockey team.

According to The Athletic's report, "Tempe Fire Medical Rescue sent crews to 400 S. Rural Road, the address for Sun Angel Stadium, at 8:31 a.m. Thursday, after receiving a report of a 'heat-related illness.' A patient was treated there and transported to a nearby hospital, the fire department said."

Mayich is a 21-year-old defenseman preparing for his second season in the NCAA and his first with ASU. He spent his first college season with Clarkson University, notching seven goals and 15 points in 34 games. Prior to that, he played for the Ottawa 67s in the OHL for four seasons.

Mayich was a sixth-round pick, 170th overall, of the Blues in the 2023 NHL draft.
