ORLANDO, Florida (AP) — 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, Dec. 23, 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.

Meanwhile in Dallas, Luka Doncic returned from a two-game absence to score 27 points, Daniel Gafford added 23 off the bench and Kyrie Irving finished with 20 as the Mavericks beat the Portland Trail Blazers, 132-108.

Doncic shot 10 of 19 overall and 1 for 7 on 3-pointers after missing Dallas’ two previous games with a left heel contusion. He had seven rebounds and seven assists.

The Mavericks have won 14 of their last 17 games following their only losing streak of the season, a four-game skid from Nov. 8-14.

Deni Avdija scored 19 off the bench to lead the Trail Blazers, who have lost eight of their last nine games. Deandre Ayton scored 16 points, including 10 in the second quarter.

The Mavericks opened the second period with a 21-9 run and outscored the Blazers 74-45 in the middle periods. They led by as many as 32 in the fourth quarter.

Earlier in Oklahoma City, Shai Gilgeous-Alexander scored 41 points and the Thunder beat Washington, 123-105, sending the NBA-worst Wizards to their 21st loss in 23 games and 12th straight on the road.

In Memphis, Norman Powell scored 29 points, including four in the final 25 seconds to lead the Los Angeles Clippers to a 114-110 victory over the Grizzlies.

With the game tied at 110, Powell hit a 14-foot jumper with 25 seconds left and then converted two free throws to give the Clippers their third win in four games. James Harden had 21 points, nine assists and eight rebounds, and Ivica Zubac finished with 20 points and a season-high 20 rebounds.
