TUESDAY, 2:55pm: Multiple reporters, including ESPN.com's Chris Broussard (Twitter link), have confirmed that Barbosa will in fact miss the rest of the season with a torn ACL.
MONDAY, 9:34pm: After suffering a knee injury in the waning minutes of the third quarter, Celtics guard Leandro Barbosa had to be helped off of the court and was ruled out for the remainder of tonight's game against the Bobcats. Now, Kevin Garnett says that the team was informed that Barbosa will be out for the remainder of the year, tweets Gary Washburn of the Boston Globe.
Losing Barbosa for the rest of the year would be a devastating blow to the C's as he was called upon to fill the void in the backcourt after Rajon Rondo's season ending injury. Boston still has Avery Bradley to pitch in at one-guard, but they will almost certainly look for additional help now that they are paper thin at the position.
