TORONTO -- Toronto Maple Leafs goaltender James Reimer is expected to be sidelined at least a week with a strained knee ligament.
Reimer suffered the injury during the second period of Toronto's 5-2 victory over the visiting Philadelphia Flyers on Monday.
The injury was diagnosed as a mild medial collateral ligament strain.
Reimer was injured while down on his knees during a goal-mouth scramble. But it's the 24-year-old Manitoba native's third injury in as many seasons with the Maple Leafs.
He missed 19 games last season with whiplash after being hit by Montreal's Brian Gionta in a game Dec. 3, 2011.
Reimer came into Monday's game with a 5-3-0 record, 2.30 goals-against average and .929 save percentage.
The Winnipeg native stopped 37 shots in leading Toronto to a 6-0 road win in Montreal on Saturday night.
