ANALYSIS: Smart suffered the non-contact injury while battling for a rebound in the fourth quarter of the 96-95 loss to the Lakers. The fiery leader of the Celtics is currently averaging 13.1 points, 6.1 assists and 1.8 steals per game.

"Marcus is essential to our team, man -- he's been great. Whether the numbers show it or not, Marcus has been a leader on this team; he's been somebody that has been looking to get guys the ball in the right spots, including me. So to have him go down in the middle of the game like that, definitely had everybody concerned. Hopefully, the MRI is negative and we get him and we can get some wins on the road."
