ORLANDO, Fla. — Tristan da Silva scored 18 points and made a critical 3-pointer with 9.9 seconds left, and the Orlando Magic rallied from a 15-point halftime deficit Monday night for a 108-104 victory over the Boston Celtics, who were missing Jayson Tatum because of an illness.

With Tatum sidelined two nights after his 43-point triple-double in a win at Chicago, Jaylen Brown led the Celtics with 35 points.

Boston led 58-43 at halftime, but the Magic dominated the third quarter to tie the game by the end of that period, and they pushed ahead by 10 in the fourth. The Celtics made a late run and Brown’s layup got Boston within 105-104 with 59.6 seconds left. Al Horford missed a potential go-ahead 3-pointer for the Celtics, and da Silva responded with his game-sealing 3.

Trevelin Queen added 17 points in his first NBA start and Jalen Suggs scored 16 for the Magic. Kristaps Porzingis and Derrick White each scored 17 for the Celtics.

Magic center Goga Bitadze was ejected with 3:36 left for stepping into an altercation between Suggs and Porzingis, both of whom drew technical fouls.
