The Celtics are still unsure whether Marcus Smart will be able to play again this season. 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.
That appears to be confirmed by this latest update, as the Celtics organization doesn't believe Irving's injury is anything overly serious.

Smart is averaging 10.2 points, 4.8 assists and 3.5 rebounds per game.
