Celtics forward Rasheed Wallace will miss a week of action with a foot injury.

Wallace missed Monday night's loss to Atlanta.

"Looks like a week, maybe," said coach Doc Rivers. "It's day-to-day, but I would say maybe a week. Maybe less. I think it's toe, foot. I'm not sure what it is. I don't know exactly. I know it started hurting him last night after the game. In the locker room he was saying his foot was bothering him. And then this morning it got bigger I guess. But when he came to the game he thought he was going to play. He actually went out and and tried to warm up, and he came in and said, 'Hey Coach, I can't go.' And we did x-rays and all that, and they were negative, but they also showed that he probably needs a break."
