UCLA guard Tyler Lamb is to undergo arthroscopic surgery on Tuesday to repair loose cartilage in his left knee. He is expected to miss four to six weeks.
Lamb was not injured during a workout, a school official said. He has been experiencing swelling in the knee recently.
"He's going to be diligent with his rehab, and we are hopeful that this will be a quick and successful procedure," Coach Ben Howland said in the statement. "He had a similar surgery on this knee the summer before his freshman year and he quickly recovered from that."
