The Toronto Maple Leafs will have to continue their playoff push without goaltender Jonathan Bernier.
Leafs coach Randy Carlyle said Friday that Bernier is out three weeks with a medial collateral ligament sprain in his left knee.
Bernier left in the third period of Toronto's 4-3 overtime win over Boston Thursday night after falling awkwardly on his left leg.
James Reimer made 10 saves on 11 shots in relief.
Bernier was making his fifth straight start since returning from a lower body injury that kept him out of five games.
The injury means Reimer will be counted on to keep the Leafs' slim playoff chances alive. Toronto trails Columbus by one point for the final playoff spot in the Eastern Conference, but the Blue Jackets have played two fewer games.
The Leafs are expected to recall goaltender Drew MacIntyre from the AHL. His agent confirmed via email that he was returning to Toronto from Utica, N.Y., where the Marlies are set to play Friday night.
MacIntyre has never started an NHL game, and even though he made one appearance in relief while Bernier was out last month, Reimer figures to be the man in goal down the stretch.
