Calgary Flames left wing Curtis Glencross is expected to miss four to six weeks with a sprained knee ligament.
Glencross injured his medial collateral ligament Tuesday in a 5-1 loss at Minnesota. Calgary called up Max Reinhart from Abbotsford of the AHL to replace Glencross before Thursday night's game against the St. Louis Blues.
Glencross has five goals and four assists in 15 games. He was appointed the team's alternate captain on Sept. 20.
