Montreal Canadiens defenceman Mike Weaver suffered a concussion in Saturday's 4-1 loss to the Dallas Stars, the team announced Monday.

Weaver left the game early in the first period and didn't return after being hit into the boards by Stars winger Ryan Garbutt.

Garbutt already served a two-game suspension last month for his hit on Edmonton Oilers forward Taylor Hall.

Weaver has four assists in 26 games with the Canadiens this season.
