Los Angeles Galaxy midfielder Clint Mathis will miss four to six weeks after having surgery to repair a torn meniscus in his left knee.

The team said Monday that Mathis was hurt in training last week and had the surgery Friday in Santa Monica.

Mathis was re-acquired by the Galaxy in January from MLS Cup champion Real Salt Lake.

The 32-year-old midfielder, in his third stint with the Galaxy, has already started his rehabilitation and could return to full training before the end of pre-season.

Mathis is expected to be ready for the March 27 season opener against New England.
