A furious, Jaylen Brown-led comeback couldn’t save the Celtics from an ugly loss Monday night at TD Garden.

Brown scored eight of his 36 points in the final three minutes to erase a 12-point fourth-quarter deficit, but the Celtics could not complete the comeback, losing to the Utah Jazz 105-103.

Neemias Queta missed a free throw with 24.8 seconds remaining, and Jusuf Nurkic scored the game-winning bucket off one of Utah’s 15 offensive rebounds on the ensuing possession. Boston’s last gasp ended with Brown being called for an offensive foul, sealing the win for a rebuilding Jazz team that was on the second night of a back-to-back.

Despite Utah playing without injured leading rebounder Walker Kessler, the Celtics were outrebounded 55-36 in the game. They also endured one of their worst 3-point shooting performances of the Joe Mazzulla era, shooting 21.6% from deep (11-for-51).

“Tough shooting night, for sure,” Mazzulla said, “but we have to be able to knock down shots.”

Doing so has been one of the biggest issues for the 3-5 Celtics this season. Only Indiana has shot worse from 3-point range than Boston’s 31.2%, which the typically reliable Derrick White (3-for-9 from three in the loss) and Payton Pritchard (4-for-11) have dragged down with uncharacteristically inefficient starts

Jazz guard Keyonte George scored 31 points on 9-of-16 shooting and went 11-for-13 from the foul line to lead the Jazz. George also was involved in the game’s most controversial play when he slipped in the final minute, causing Brown to stumble over him and lose possession.

George was not called for a foul on the play, which Brown said was “unacceptable” and “some (BS).”

Boston will look to bounce back against another projected lottery team when the Washington Wizards visit Causeway Street on Wednesday (7:30 p.m.).

The Celtics sprinted out to a double-digit first-quarter lead fueled by 3-pointers from White, Pritchard and Sam Hauser. Hauser had been his usual efficient self from beyond the arc this season (45.1% entering Monday), but the hot start appeared encouraging for White and Pritchard, who entered the game ranked second-to-last and last in 3-point shooting percentage among all NBA players with at least 35 attempts.

Then, the threes stopped falling, and that Celtics cushion quickly evaporated. After jumping ahead 10-0, Boston proceeded to miss nine of its next 10 3-point attempts, including five straight misses by Brown. Utah got to within three late in the first quarter and tied the game at 27-27 early in the second.

Neither White nor Hauser made another triple until midway through the fourth quarter, combining to miss 10 straight after their early makes. Pritchard started 3-for-4 from deep but misfired his next six.

White has made just 20 of his 76 3-point attempts this season (26.3%). Pritchard is off to a 13-for-61 start (21.3%). Both have helped the Celtics in other ways, but they haven’t come close to matching their long-range efficiency from last season, when they ranked fourth and fifth in the league in made threes while shooting a combined 39.4%.

“I thought I was (expletive) today, honestly,” White said. “So I think I’m a big reason why they got back in that game.”

After Utah’s rally, Anfernee Simons (15 points) gave the Celtics some breathing room with three big plays in quick succession. The undersized sixth man played quality defense on a driving Lauri Markkanen to help force a turnover, then buried 3-pointers on back-to-back Celtics possessions.

Josh Minott, making his fifth consecutive start for Boston, followed those up with an acrobatic putback dunk off a Brown miss. Minott also was the player primarily responsible for defending Markkanen — the only recent All-Star on Utah’s roster — and the 7-foot-1 big man managed just six first-half points on 3-for-12 shooting. Overall, it was one of the best defensive halves of the season for the Celtics, who held the Jazz to 36 points on 31.3% shooting and led by 10 at halftime despite shooting just 39.1% themselves (and 7-for-28 from three).

Fouls were an issue for Minott, however; he picked up three in the first half and another nine seconds into his first third-quarter shift, limiting his playing time.

The opening nine minutes of the second half were a slog for the Celtics, who looked disjointed offensively and struggled to corral George. The third-year guard converted multiple driving layups over White, the NBA’s top shot-blocker at his position, and drilled a step-back three while being blanketed by Baylor Scheierman. Markkanen began to heat up, as well, and Utah pulled ahead for the first time.

“(The third quarter was) just bad,” White said. “I don’t know exactly what happened, but bad communication, bad rotations. They kind of did whatever they wanted that quarter, and that’s been kind of like the whole year. There’s always been that one quarter that seems to get us.”

The Celtics got the spark they needed when, after Mazzulla called a timeout with his team trailing 66-61, Brown scored two contested 2-pointers in 13 seconds, drawing a foul on the second. Those bookended a standout defensive play by Scheierman and Chris Boucher, who raced back to foil a fast break by Ace Bailey.

Boucher then hit a 3-pointer — his first in a Celtics uniform after an 0-for-8 start to his tenure — to put Boston up 70-66. But that also was the only three any Celtics player made in the third quarter — or the first several minutes of the fourth, for that matter. By the time White and Pritchard finally regained their rhythm with threes on consecutive trips, the Jazz had built a 12-point lead with just over seven minutes to play.

“They got the best of us,” Mazzulla said. “They just played better. They played harder and better than we did during that quarter.”

Brown’s 3-point stroke never materialized (he finished 0-for-9 from deep), but he keyed Boston’s rally by aggressively attacking both the basket and Utah’s ball-handlers. He made three field goals at the rim in the final 5:13 and drew a foul on another, setting up one of his buckets by stealing the ball from Elijah Harkless at the other end.

Six straight points from Brown trimmed Utah’s lead to one with 2:20 remaining, and a three by White put the Celtics ahead 99-98. But Boston couldn’t close.

“We’ve got to get the rebounds at the end of the game,” Brown said. “They’re crucial. And then in moments, it just felt like they were the harder-playing team. I guess it’s just a part of our learning curve, I guess. Teams shouldn’t — especially a team coming off a back-to-back — shouldn’t be a harder-playing team than us. I’ve got to lead the way on both ends of the ball. So I guess I’ve got to be better in that regard, as well.”
