Mavericks 15-22 Celtics; 5.24, first quarter

Brown cans a pair of free throws to put Boston back ahead, but Doni answers with a driving lay-up with Celtics all over him, appealing to the referees over the no-call. The Mavericks have made seven of their first 10 shots from the floor but only lead by one. From there White makes back-to-back three-pointers. Then Porzingis draws a shooting foul on Doni and makes both freebies to open a seven-point lead.
