The loss of Smart could be potentially devastating for the Celtics.
Smart will head to the Big Apple to have another examination done on his right thumb, according to NBA.com's David Aldridge.
To be more accurate, the injury occurred when Smart went for a diving steal in what was ultimately a 99-97 Boston lost to Indiana Sunday. Those are questions only Smart and the Celtics' doctors. Smart is now going over his treatment options with the Celtics medical staff, but with no clear timetable to return, he should be sent to the waiver wire in most cases.
Smart is averaging 10.2 points, 4.8 assists and 3.5 rebounds in 29.9 minutes this season.
