Smart has been diagnosed with a left ankle sprain and a bone bruise, and the initial estimate is that he will miss two-to-three weeks, the Boston Herald's Mark Murphy reports. This is about the best news Smart's owners could hope for, as he was seen in a wheelchair after the game, and the thought was that it was a very severe ankle sprain. In Smart's absence, Avery Bradley will likely take on a slightly larger workload, with Phil Pressey serving as the backup point guard behind Rajon Rondo, who is out Saturday to have a screw removed from his hand, incidentally.
