Philadelphia 76ers general manager Tony DiLeo said Saturday that center Andrew Bynum is out indefinitely with a recurring knee injury and there is no timetable for his return, reports ESPN.com.

The Sixers had hoped for Bynum to return to the team in mid-December for practice. DiLeo said the team is doing everything possible to get Bynum back on the court.

"It sucks; I just don't know what to expect," Bynum said last week. "I have an issue with my knees and we're trying to resolve it. There's no surgical procedures that will really help or are safe to do at the moment. I've just got to bide my time."

Bynum has not played this season and said that his left knee swelled after he went bowling last Saturday night. An MRI revealed that Bynum had new damage in the knee. Bynum missed the Sixers' entire training camp and preseason with a bone bruise in his right knee.
