Lakers center Andrew Bynum has acknowledged that there is a "possibility" that he could be out until December.

Bynum is rehabbing his knee once again and it was originally thought that he'd return by the middle of November.

"Yeah, it's a possibility," he said of returning in December. "I've got a little bit of pain still. It just depends on when I'm cleared."

Bynum said he would see his doctor in three weeks. He had knee surgery in July.

"He's been saying that," coach Phil Jackson said. "I don't know why he's talking about December. He can get weight-bearing activities started at the end of this month. Can you play in two weeks [after that]? Can you play in three weeks? Four weeks puts you at the end of November. So let's just let it happen and not talk about what the timing is."
