TORONTO, March 15 (UPI) -- Doug Gilmour's second tenure with the Toronto Maple Leafs may wind up being a brief one.
Gilmour will be sidelined four to six weeks with a left knee injury, General Manager and Coach Pat Quinn announced Saturday.
A former Maple Leafs' captain, Gilmour was re-acquired from the Montreal Canadiens at Tuesday's trade deadline. In his first game with his old team, the 39-year-old center collided with Calgary Flames left wing Dave Lowry and crawled on his knees back to the bench. He left the Saddledome on crutches.
An MRI taken Friday revealed the extent of the damage, Quinn said. A six-week injury would carry through the second round of the playoffs.
Gilmour has 11 goals and 19 assists in 62 games and has hinted he will retire at the end of the season.
