Doc Rivers considered Kendrick Perkins 50-50 for last night's game against the Bulls, figuring the young big man will have to miss some time to allow the plantar fasciitis in his left foot to heal. After Perkins played 15:45 in the Celtics' 100-82 loss, Rivers said a time for that decision was drawing close.

For better or worse, Perkins wants to stay on the floor as much as possible.

"It's a little better, but it's still sore," said Perkins, who had 2 points and 3 rebounds. "I've just got to wait and see. I know in order for it to heal you have to have rest, but I ain't thought about sitting out any games. I barely want to sit out practice."

"Perk's is a concern because that's more than a nagging injury," said Rivers. "Right now, it's a nagging injury, but it usually turns into something worse. I've never had it. I don't think I've ever had a player who's had it."

"I just don't know how to handle this one. At some point, if it doesn't improve at all, I'm pretty sure we're going to go down that road of just making a decision [to rest him]. He would have no choice."

"I hope that doesn't happen. But if I was taking bets, I would say it probably will."
