Andrew Bynum is experiencing pain in his left knee, which may postpone his return until March.

Bynum had been targeting his debut with the Philadelphia 76ers by the end of February.

Bynum said he “worked hard for two days on the court and then I got a lot pain, so we backed down a little today. I’ll probably go on (the anti-gravity machine Tuesday).”

While Bynum added he’s “not really optimistic,” the pain “limits” what he does and shows he’s “not ready yet,” he also claimed Sunday’s pain doesn’t signify a setback.

“I hope it’ll keep going like that and I’ll be back soon,” Bynum said. “When I get on the court, that’s when I want to be ready. I’m trying as hard as I can. It would suck to play through pain, but sometimes you have to.”
