The Celtics could be without the Defensive Player of the Year when the Eastern Conference Final tips off tonight in Miami.
According to head coach Ime Udoka, Marcus Smart is questionable for tonight's Game One with a right midfoot sprain.
Smart underwent an MRI on Monday that came back clean, and the Boston guard will test the foot before tonight's game.
The C's will have center Robert Williams available with no restrictions heading into the series.
Tip Off is set for 8:30 tonight in Miami.
