Toronto Maple Leafs forward Joffrey Lupul left Wednesday's game against the Boston Bruins after a collision and did not return.

Lupul was involved in a collision in the neutral zone, hobbled off the ice and needed assistance from team trainers to make it to the dressing room.

Seen on crutches after the game, Lupul is returning to Toronto for an MRI on what appeared to be a left leg injury.

In 25 games this season, Lupul has nine goals and eight assists for 17 points.
