Smart is considered questionable for Monday's game against the Raptors due to a sprained right thumb.
EDGE Analysis
Smart picked up the injury during Sunday's narrow win over Detroit, in which he had 17 points and a season-high 10 assists. There's a chance he'll be held out on the second night of the back-to-back, which would leave the Celtics shorthanded with Jeff Teague (ankle) and Kemba Walker (knee) already ruled out.
