The worst-case scenario for Leandro Barbosa‘s knee appears to have been confirmed. The Celtics guard, who came up lame during Monday’s loss in Charlotte, reportedly has torn the ACL in his left knee. Such an injury would end his season.

Kevin Garnett told reporters in the locker room after the game that the team was informed Barbosa would join Rajon Rondo and Jared Sullinger on the sideline for the rest of the season. Sources confirmed that diagnosis to Steve Bulpett of the Boston Herald.

More sources saying what we've already been hearing: Testing being done, but it's looking like an ACL for Barbosa.
