BOSTON >> Jaylen Brown had 36 points and 10 rebounds, Kristaps Porzingis returned to the game after getting a bloody gash to the forehead and finished with 20 points, and the Boston Celtics beat the Orlando Magic 109-100 in Game 2 of their first-round playoff series on Wednesday night.

Boston took a 2-0 series lead while playing without All-Star Jayson Tatum, who has a bone bruise in his right wrist and missed a playoff game for the first time in his career.

Boston led by 15 points in the second half, then held off a late push by Orlando. The Celtics hit 12 3-pointers and went 25 of 33 from the free-throw line. Derrick White and Brown had 17 of Boston’s 28 points in the final period; White finished with 17.

Paolo Banchero led the Magic with 32 points and nine rebounds. Franz Wagner scored 25 points.

Game 3 is Friday night at Orlando.

Tatum had not missed a playoff game in his eight seasons with Boston. He injured his wrist in Game 1 after landing awkwardly following a flagrant foul by Kentavious Caldwell-Pope.

Clad in street clothes, he joined his team prior to tipoff and sat at the end of the bench.

Boston coach Joe Mazzulla characterized Tatum’s status as day to day.

Caldwell-Pope was booed nearly every time he touched the ball in the aftermath of his Game 1 foul on Tatum, which the Celtics’ Al Horford later characterized as excessive.

Tempers flared between Caldwell-Pope and Horford when their feet got tangled up and sent both crashing to the floor at the 4:42 mark of the second quarter.

Brown then exchanged words with Caldwell-Pope. Referees reviewed the play and determined it was a common tripping foul on Caldwell-Pope.

Then, late in the third quarter, Porzingis went to the locker room with a gash to his forehead but returned in time to shoot a pair of free throws after taking an elbow from Goga Bitadze. The play was reviewed and upgraded to a flagrant foul on Bitadze

Cavaliers 121, Heat 112 >> Donovan Mitchell scored 30 points, including 17 in the fourth quarter, and Cleveland held on for a victory over Miami for a 2-0 lead in its Eastern Conference first-round series.

The top-seeded Cavaliers set an NBA playoff record with 11 3-pointers in the second quarter and had 22 for the game. However, Cleveland had to hold off a second-half charge by Miami.

Tyler Herro scored 33 points for Miami, which hosts Game 3 on Saturday afternoon.

The Cavaliers had a 19-point lead with under 3 minutes remaining in the third quarter before the Heat made their run to get within 105-103 lead with 3:11 left.

Mitchell, who also had six rebounds and six assists, then put the game on his shoulders. He scored Cleveland’s next eight points, including a pair of 3-pointers, during an 8-2 run to give them some breathing room.

Evan Mobley had 20 points and Darius Garland 19 for the Cavaliers.

Miami had a 16-7 lead before the Cavs rallied and went up 25-24 at the end of the first quarter.
