Rajon Rondo, the Boston Celtics' All-Star point guard, is out for the season with a torn anterior cruciate ligament in his right knee.
The Celtics, who snapped a six-game losing streak with a 100-98 double-overtime victory over the Miami Heat in his absence Sunday, announced the news after Rondo left TD Garden before the game.
Rondo injured the knee on Friday night while playing the Atlanta Hawks, who came back from a 27-point deficit to win in double overtime.
The injury was originally called a hyperextension, but Rondo felt discomfort in the knee during the Celtics' morning shoot-around Sunday. He was taken to a hospital, where an MRI exam revealed the torn ligament.
