Montreal Canadiens defenseman Shea Weber will undergo surgery to repair a tendon in his left foot and has been consequently ruled out for the remainder of the 2017-18 season, the team announced Thursday.

Weber hasn't played since Dec. 16.

"Following the diagnosis of Shea Weber's injury, it was our belief that after a comprehensive rehabilitation protocol under the guidance of our medical team, Shea would be able to return to play this season. Unfortunately, after extensive efforts to heal Shea's injury, progress has not been made as expected," said Canadiens orthopedic surgeon, Dr. Paul Martineau.

Weber, 32, is in his second season with the Canadiens and is under contract until 2025-26 with an annual cap hit of $7.857 million. Before he was injured, he had recorded 16 points in 26 games on Montreal's top defensive pairing.
