Former Sheffield Steelers coach Dave Matsos collapsed on the bench in the final minute of a Hamilton Bulldogs game on Saturday.
The 44-year-old appeared to be unconscious for several minutes while being assessed and treated by medical staff in Canada.
It is thought he may have had a heart attack,
“He was alert and responsive when transported to a local hospital for ’precautionary measures.’” said an official.
The Ontario Hockey League game was called off.
