The Heat and Celtics are dealing with injury problems ahead of Game 3. Tyler Herro has been ruled out for Miami, while Marcus Smart and Robert Williams are questionable. Kyle Lowry's return made all the difference for Miami on defense in Game 2, and the visitors can stay close if one of both of the Celtics' defensive anchors are ruled out. Miami's only lost two road games by more than seven points when Lowry, Jimmy Butler, and Bam Adebayo are active this season.
