Bynum: 'I think it happened bowling'

Philadelphia 76ers center Andrew Bynum admitted before Sunday's game with the Cleveland Cavaliers that he might have injured his left knee bowling one week ago Saturday.

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

On Friday Bynum, who has been trying to rehabilitate his right knee (bone bruise) told reporters that a trip to see Dr. David W. Altchek in New York revealed that he also has a bone bruise on his left knee and that the cartilage in both knees are in a weakened state.

Late Saturday night, ESPN.com cited multiple sources saying that Bynum had suffered the latest injury – and exacerbated the cartilage situation – while bowling.

Bynum said this was not this was not the first time he as bowled since the start of training camp, when the Sixers announced that he would not participate. Acquired in a four-team trade over the summer, Bynum has yet to play for the Sixers.

On Friday Bynum said he still hopes to return to basketball-related activity by mid-December and hopefully back to playing games by mid January. Bynum last played in an NBA game last May. E

According to Bynum 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. "

Asked if he knew anything about the bowling situation, Sixers coach Doug Collins said, "no."

Bynum said he noticed swelling in his knees after the injury. He also questioned the wisdom of bowling under the circumstances.

"In hindsight, I guess you really shouldn't go bowling but it's not anything more than what I've done in my rehab," Bynum said.

He then added: "I'm kind of taking the position that if that happens bowling, what happens while dunking?

It is the multi-million dollar question.
