Coyotes General Manager Don Maloney says the 23-year-old MacLean received CPR on Monday night at the rink in Owen Sound, Ontario. He was taken to a hospital by ambulance, then transported by air ambulance to Knight University Hospital in London, Ontario where he was admitted to cardiac ICU.
Maloney says no other information was available Tuesday.
He was claimed off waivers by Winnipeg last Oct. 5, then waived by the Jets 23 days later. Phoenix reclaimed MacLean and assigned him to AHL Portland.
