The San Jose Sharks announced Tuesday that captain Joe Thornton underwent successful surgery to repair two damaged ligaments in his left knee.
Thornton underwent the surgery Monday. The Sharks said he is expected to make a complete recovery and be ready for the start of his 21st season.
Thornton's next season might not be with the Sharks. He is an unrestricted free agent this summer and the surgery requires about a six-month recovery.
The Sharks announced Thornton's injuries Monday after reports surfaced that he played four postseason games against the Edmonton Oilers with a torn anterior cruciate ligament and torn medial collateral ligament.
The 37-year-old was injured April 2 against the Vancouver Canucks. He missed the rest of the regular season games and the first two games against Edmonton.
Thornton, who won the Hart Trophy as the NHL's Most Valuable Player in 2006, totaled seven goals and 43 assists in 79 regular-season games this season.
