Lakers center Andrew Bynum is progressing quicker than expected in his return from surgery performed on his right knee in July.

Bynum ran on the treadmill Sunday with his full body weight on the knee, graduating from an altered gravity machine that he had been using to ease himself back into playing condition.

"He went through some activity that was accelerated," Los Angeles coach Phil Jackson said.

"I think he wants to ramp it up a little bit faster than we want him to. We want him to be able to go in and sustain that effort when he does get back, so he needs to have a real base. He needs a foundation to come back and play with. ... We want him back tomorrow, but if he's back in two, three, four weeks, we understand what it's going to take."

Jackson said the team is hoping that Bynum will return around Thanksgiving.
