Bruins' McAvoy leaves game vs. Habs with lower-body injury

Boston Bruins defenseman Charlie McAvoy left Saturday's game in the first period against the Montreal Canadiens with a lower-body injury and is not likely to return, the team announced.

McAvoy left the game just 37 seconds in after appearing to be tripped by Canadiens forward Brendan Gallagher.

"It's a lower-body injury ... team is off tomorrow, we'll have a better idea on Monday," head coach Bruce Cassidy said postgame. "Hopefully it's not serious."

An injury of any severity would be a big blow to the Bruins as the 20-year-old sits second in team scoring among defensemen with 32 points in 58 games.
