Boston: Al Horford had 21 points in his return from a two-game absence for a concussion and the Boston Celtics hung on to beat the Toronto Raptors 95-94 on Sunday for their 12th straight victory.

Boston (12-2) were playing without Kyrie Irving after he took an inadvertent elbow to the face from teammate Aron Baynes on Friday night against Charlotte. Irving has a minor facial fracture but has not been diagnosed with a concussion as initially feared.

Jaylen Brown added 18 points, and Terry Rozier helped fill in for Irving with 16 points off the bench. Boston shot just 40.2 per cent from the field.

DeMar DeRozan scored 24 points, and Kyle Lowry had 19 points and seven assists for Toronto. The Raptors dropped to 7-5 after winning two straight.

Jayson Tatum’s acrobatic layup with 1:26 remaining in the fourth quarter put the Celtics up 95-90.

DeRozan missed a potential go-ahead stepback jumper with 19 seconds remaining. Tatum got the rebound, but elbowed Fred VanVleet in the face for an offensive foul that was confirmed by video review.

DeRozan had another look to give Toronto the win, but missed a turnaround jumper with 2 seconds left. Serge Ibaka scooped up the rebound, but lost the ball as time expired.
