Brendan Gallagher exited Wednesday's game versus the Dallas Stars when he was struck on the left hand by a shot from teammate Shea Weber.
The Montreal Canadiens forward was in obvious pain, and was incensed as he left the ice and headed toward the tunnel for treatment.
Gallagher missed six weeks last season after suffering fractures to his left hand blocking a shot from New York Islanders defender Johnny Boychuk.
Head coach Michel Therrien announced after the game that Gallagher will fly to Montreal to undergo examination, meaning he won't be available for Saturday's game versus the Toronto Maple Leafs.
