TORONTO (AP) Kyle Lowry and DeMar DeRozan each scored 18 points, Patrick Patterson had 17 and the Toronto Raptors beat Boston 116-109 on Friday, handing the Celtics their first defeat in three preseason games.
Toronto guard Terrence Ross returned to the starting lineup after sitting out Tuesday's loss at Sacramento with a sore right knee, while Patterson (right hand, right knee) played for the first time in three preseason games.
Center Greg Stiemsma, who suffered a concussion Tuesday, was unable to play after failing to pass a league-mandated test. Stiemsma will be tested again Saturday.
Before the game, Celtics coach Brad Stevens said injured guard Rajon Rondo (broken left hand) has begun to participate in non-contact practice drills. Stevens also said he would have an update Saturday on center Vitor Faverani, who has missed all of training camp with a sore left knee.
The teams meet again Wednesday in Portland, Maine.
