Habs announce Gallagher done for the night
— Eric Engels (@EricEngels) March 6, 2016
Gallagher fell awkwardly after a collision and subsequently left the ice.
Earlier in the game, he also appeared to take a puck off a hand. The 23-year-old missed an extended period of time this season when he fractured two fingers on his left hand.
It’s not immediately clear which instance caused him to leave the game.
