Boston Celtics forward Leon Powe is out for the rest of the season with a torn knee ligament.
The Celtics are already without Kevin Garnett as they try to defend their unprecedented 17th NBA title.
The Celtics beat the Chicago Bulls 118-115 on Monday night to even their best-of-seven first-round series at one game apiece. Powe hurt himself on a spin move but stayed on the court three more minutes trying to play.
Celtics point guard Rajon Rondo is sitting out practice Tuesday and Wednesday with a sprained ankle. But coach Doc Rivers says Rondo will be able to play in Game 3 on Thursday night.
