In September, Bynum had injections of platelet-rich plasma in an effort to stimulate healing in arthritis-affected areas in his knees.
Bynum was acquired from the Los Angeles Lakers in a four-team deal in August. He has been held out of 76ers training camp.
The Sixers' shape. After the Sixers lost a 108-105 overtime decision to the Brooklyn Nets Saturday in Atlantic City, Collins said the team has some players who need to get in better shape.
On Sunday during an afternoon practice at Philadelphia College of Osteopathic Medicine, Collins wanted to make it clear that his team is not some poorly conditioned bunch with the start of the season approaching on Oct. 31.
"I think we are overplaying this lagging behind in conditioning; that's not what I said," Collins said. "We've got some guys that I'd like to see get in better condition. We have got to be a better and more highly conditioned team. That doesn't mean we're not in good condition. I want us to be a highly conditioned team. To me, that's a huge difference."
Collins has yet to say any player's name specifically. However, it is clear that Kwame Brown and Lavoy Allen could stand to be better conditioned at this point. Brown suffered a strained calf Sunday and might not be available for Monday's home preseason game against Boston.
Brown has been working to get his weight down, and so has Allen. Collins hopes that Brown will not have a huge setback and can quickly get back to preparing for the season. Allen is heavier than he was last season. Also, he missed some crucial conditioning last week because of the birth of his first child. Both players have been doing extra running in practice.
