Phil was on AM570 yesterday and basically agreed they expect Bynum back in a couple of weeks.
Also, from Today's (2/26) LA Times:
Bynum said there wasn't much swelling left in the knee, that he's walking "normally" and that he worked on his strength and balance Monday.
He is running in the swimming pool.
When Bynum was first injured, the Lakers said he'd be out a minimum of eight weeks. But there now is no timetable for his return, though he's not expected back until some time later in March.
"There's no pressure on me to come back," Bynum said. "I definitely want to get back 100 percent. That's what I plan to do, however long it takes. I still that I could make the eight-week deadline, but I'm not going to force it."
