PHILADELPHIA -- Saying Andrew Bynum's knees "are not the same" as when they traded for him in August, the Philadelphia 76ers are now not sure when Bynum will be able to play for them -- if he plays for them at all.

Two weeks after the team announced they hoped Bynum would be cleared to return to practice on Dec. 10, Sixers general manager Tony DiLeo said Saturday the team no longer has any timeline for Bynum to return.

"Bottom line is Andrew is out indefinitely," DiLeo said before the Sixers played the Oklahoma City Thunder. "There are no timelines; we just have to wait and see how he reacts."
