National Hockey League linesman Tyson Baker warned of a potentially serious injury during Wednesday night’s game between the Nashville Predators and the Calgary Flames.
Former Canadiens Michael McCarron threw down the gloves in the first period with Flames defenseman Dennis Gilbert.
Gilbert lost his helmet during the fight. Therefore, he fell completely without head protection towards the end of the duel, knocked down by McCarron.
Linesman Baker then had the life-saving reflex of putting his hand behind his head when it hit the ice hard.
