Gay, Lowry and Amir Johnson played the entire first quarter, but spent the rest of the night on the bench. DeMar DeRozan joined them after playing just over one minute in the second.
The Raptors used a 10-0 run in the final 4:36 of the third quarter to take an 80-70 lead into the fourth. Boston missed seven straight field goal attempts after Green's dunk with 4:50 to go in the third put them up 70-69, their final lead of the game.
Brooks hit a 3 with 24 seconds left to cut it to 97-95, but Julyan Stone answered with a pair of free throws for the Raptors. Stone then missed a layup with seven seconds to go, setting up the frantic finish.
