Boston Celtics forward Leon Powe has undergone surgery for a microfracture and torn ligaments in his left knee.
The team announced that team physician Dr. Brian McKeon performed the surgery Tuesday morning at New England Baptist Hospital.
No timetable has been set for Powe's return.
The third-year forward tore his anterior cruciate ligament and meniscus in the first quarter of the Celtics 118-115 win in Game 2 of their first-round playoff series against the Chicago Bulls on April 20. The defending NBA champions won the series in seven games.
Coach Doc Rivers said Powe hurt himself on a spin move but continued playing for three more minutes.
Powe averaged 7.7 points and 4.9 rebounds per game this season.
