Boston Celtics guard Leandro Barbosa has a torn anterior cruciate ligament in his knee and will be out for the rest of the National Basketball Association season, his club said Tuesday.
The 30-year-old suffered the left knee injury during Monday's game against the Charlotte Bobcats.
He underwent a magnetic resonance imaging scan but no surgery date has been set, the club said.
He is the third Celtics player lost for the season due to injury. Rajon Rondo also suffered a torn ACL last month and back surgery has put out Jared Sullinger.
The six-foot-three (1.9-meter) guard has played in 41 games this season, averaging 5.2 points and 1.4 assists per game.
In nine seasons with Phoenix, Toronto, Indiana and Boston, Barbosa has averaged 12.0 points and 2.4 assists per game.
