The Lakers are again trying to get Andrew Bynum back to full speed.

Bynum sat out Tuesday's game against Houston because of a bone bruise in his left knee, and in Thursday's loss to San Antonio he didn't produce the way coach Phil Jackson wanted.

"Drew, historically he's been good at running, post-sprinting," Jackson said. "He hasn't done much of that lately, and that's an important part we have to get back."

Bynum sat out the first 24 regular-season games recovering from right knee surgery and he's still working on his conditioning.

"We're about him getting the position, blocking shots, being active, challenging people coming into the lane," Jackson said. "Those type of things."
