Celtics captain Paul Pierce is expected to miss the next two weeks of the season after undergoing minor right knee surgery Wednesday.
Pierce was admitted to New England Baptist Hospital to undergo a procedure to drain an infection, the morning after scoring 21 points in the Celtics' 103-94 win over Indiana.
"Paul felt fine after the game," Celtics president of basketball operations Danny Ainge said. "He felt great. A few hours later there was swelling and pain, and so they put him through some tests this morning. Then, they went in and they felt like they needed to clean out the infection. It's nothing structural, and it's a guess, but they are saying two weeks. I'm always when worried when a player gets hurt but the good news is there was no structural (damage)."
Ainge said Kevin Garnett (right thigh bruise) is expected to return soon, following a one-game absence. Garnett arrived with the team in Orlando Wednesday afternoon.
"I don't know when for KG," Ainge said. "He may play, but it will be a game-time decision Friday. I think he's fine -- it's not anything structural. He wanted to play (Tuesday) night but we're being cautious."
The Celtics called up Bill Walker from the Maine Red Claws to replace Pierce.
"Billy has been playing well," Ainge said. "I didn't want to bring him up right this minute, because he's making great progress and he's getting a chance to develop there. But, now there may be an opportunity for him here."
