New Details Emerge on Workout That Left NHL Prospect with ‘Zero Chance of Recovery’: Reports

Two new reports provide details about the workout that left NHL prospect Matthew Mayich in the hospital

Mayich was reportedly "disoriented" during the bear crawl portion of the workout and collapsed during the final exercise

The 21-year-old has "zero chance of recovery," his attorney said earlier this month

NHL prospect Matthew Mayich struggled to stand multiple times before collapsing during the military-style workout with the Arizona State Sun Devils that left him hospitalized, witnesses allege in two new reports.

A report from The Athletic , published Thursday, Sept. 16, provides new details about the workout led by Tim Ziesel, a former Green Beret unaffiliated with Arizona State who was brought in to run a special workout with the hockey team on Aug. 20, their first day of organized practices.

Ziesel, who reportedly had a "handshake agreement" with head coach Greg Powers to lead the Sun Devils' practice according to Arizona Republic reporter Robert Anglen, took the team through different movements, such as squats and push-ups, at Sun Angel Stadium, the university's unshaded track and field facilities.

According to The Athletic, which interviewed 12 people either at the workout or briefed on it, Mayich, 21, appeared "disoriented" while doing bear crawls across the field. The witness told the outlet Mayich appeared to catch himself before he almost collapsed after that exercise.

Two other players on the team vomited during the workout, The Athletic reported.

Ziesel reportedly belittled players during the workout, according to The Athletic, and he left after assigning the final event of the workout — a relay race requiring players to carry a medicine ball.

Mayich was reportedly one of the last players to begin the race, and he collapsed after stumbling and dropping the ball, sources told The Athletic. He reportedly attempted to get up twice before collapsing a final time.

Sources told the outlet that one player and an assistant coach shouted for assistance before teammates "found him lying on the ground, incoherent and distressed, unable to respond to questions."

Mayich remained in the sun for several minutes after he collapsed. Four of his Sun Devils teammates reportedly then carried him into the shade and an athletic trainer retrieved water and an ice pack to put on his chest, according to The Athletic. An ambulance arrived at the stadium at 8:31 a.m., around an hour and a half after the workout began, the outlet said.

Rob Carey, the attorney representing the Mayich family, told ESPN the sophomore athlete suffered "exertional heat stroke that caused a lack of oxygen to the brain."

"There were no other contributing conditions, only exertion-related heat. This is not an induced coma," Carey told the outlet, adding, "We need a miracle."

Carey told the Arizona Republic on Sept. 1 that Mayich has "zero chance of recovery."

PEOPLE has reached out to Ziesel's attorney for comment.
