Andrew Bynum will undergo surgery July 28 to mend the torn meniscus in his right knee, the Lakers announced on their website. Bynum suffered the tear during the Lakers’ opening-round playoff victory over the Oklahoma City Thunder in April. His strength and mobility suffered as did his production, but he did not miss a playoff game as the Lakers went on to win their second consecutive NBA title. He averaged 8.6 points and 6.9 rebounds in the playoffs, down from his regular-season totals of 15 points and 8.3 rebounds. Bynum’s surgery was said to be minor and he is expected to be fit by the start of training camp in late September.
