Montreal Canadiens forward Max Pacioretty left Sunday’s game against the Florida Panthers after hitting his head hard into the boards.
The team has announced he will not return.
The incident occurred midway through the first period, when Pacioretty was clipped by Panthers defenceman Dmitri Kulikov, sending him awkwardly into the boards.
He was visibly shaken and slow to get up.
The extent of the injury is not yet known. The loss of the winger would be a huge blow to the Canadiens, especially so close to the playoffs.
Pacioretty ranks first on the team in goals and game-winning goals and fifth in assists.
