The Calgary Flames will be without backup goaltender Henrik Karlsson for 6-8 weeks due to a high-grade tear of the medial collateral ligament in his right knee.
Karlsson suffered the injury during Sunday's game against Vancouver when teammate Tom Kostopoulos fell into him. Karlsson went down clutching his knee and was removed from the game.
Karlsson has played just six games Miikka Kiprusoff's backup, going 0-4-1 with a 3.48 goals-against average and .895 save percentage.
The Flames have recalled goalie Leland Irving from AHL Abbotsford to serve as Kiprusoff's backup.
