All in all, Monday proved to be a painful night for the Boston Celtics.

Not only did the Celtics have their seven-game losing streak snapped at the hands of the NBA’s worst team, but they might have suffered yet another costly injury in their 94-91 loss to the Charlotte Bobcats.

Backup guard Leandro Barbosa, who has seen increased playing time since the season-ending injury to Rajon Rondo, injured his left knee late in the third quarter and had to be carried to the locker room by a trainer and teammate.

Coach Doc Rivers said Barbosa will have an MRI on Tuesday.

”It doesn’t look great but we’ll see,” Rivers said…

This night belonged to Charlotte’s unheralded big man, Byron Mullens…

The 7-foot Mullens hit 10 of 16 shots from the field, including 4 of 5 from 3-point range. Ramon Sessions had 19 points for the Bobcats, including the go-ahead jumper from 18 feet with 25.7 seconds left. Kemba Walker had 18 points, six assists and six rebounds, and Gerald Henderson chipped in with 16 points…

Kevin Garnett had 16 points and 13 rebounds for the Celtics, but missed a key 18-footer that would have given Boston the lead late in the game. Paul Pierce and Avery Bradley had chances to send the game into overtime in the final seconds, but missed open 3-pointers.

Jeff Green had 18 points for the Celtics and Pierce finished with 13 points, eight assists and eight rebounds…

Bobcats center Bismack Biyombo was a force inside on the defensive end blocking four shots and grabbing seven defensive rebounds.
