Nowitzki (Achilles) has been deemed a game-time decision for Wednesday's game against the Celtics, Gary Washburn of The Boston Globe reports.
A sore right Achilles has kept Nowitzki out of the last four games, and it remains to be seen whether he'll be able to make his return Wednesday night. A decision likely won't come until close to game time after he's had a chance to test the Achilles during warmups, but it was encouraging that he was at least able to take part in three-on-three work during Tuesday's practice. If Nowitzki is again held out, Dorian Finney-Smith would likely make another start, while Dwight Powell would be in line for increased minutes off the bench.
