Philadelphia 76ers center Andrew Bynum has swelling in his injured right knee and says he does not know if he'll play this season.

Bynum has yet to play for the Sixers because of bone bruises in both knees. Bynum says he has swelling in his right knee from a five-on-five scrimmage last week.

Bynum has said all along he would play this season. But for the first time on Friday, he says, "I don't know." He is in the final year of his contract and says he won't be pressured into making a decision to play or sit out.

Bynum says, "I don't want to play in pain."
