Ducks defenseman Toni Lydman had successful surgery to repair torn cartilage in his left knee, a team spokesman said Monday.

Team physician Dr. Orr Limpisvasti performed the surgery on Monday. Recovery time is expected to be approximately four weeks and Lydman should be ready for training camp in September.

Defenseman Francois Beauchemin is expected to undergo arthroscopic surgery on his right shoulder this week, with Dr. Ronald Glousman performing the procedure. Beauchemin said last week that he expects it won’t be as severe as the one Lydman had which kept him out of camp last fall.
