Andrew Bynum admitted on Sunday that he may have sustained a left knee injury while bowling.

“It’s the same exact injury, mirror images of the knee; I think it happened bowling, to be honest,” Bynum said.

Bynum contends that he did not suffer any trauma to the knee.

“I didn’t twist it, didn’t fall – nothing,” Bynum said.  “It’s weird because I was doing low-impact training and squatting and then I go out and hurt myself like this. It’s very frustrating."
