Jayson Tatum has not missed a playoff game in his eight-year NBA career. That streak is likely to end Wednesday night at TD Garden.

The Celtics listed Tatum as doubtful for Game 2 of their first-round playoff series against the Magic with a right distal radius bone bruise in his wrist. He suffered the injury late in Game 1 on Sunday on a hard foul from Orlando guard Kentavious Caldwell-Pope.

Caldwell-Pope grabbed Tatum’s elbow while the latter elevated for a dunk midway through the fourth quarter. Tatum landed awkwardly on his wrist, and Caldwell-Pope was called for a Flagrant 1 foul.

Tatum remained down for an extended period and was briefly examined during the ensuing timeout, but he remained in the game and downplayed the injury afterward, saying he was “good” and that X-rays on his wrist came back “clean.” The Celtics won 103-86 to take a 1-0 series lead, with Tatum playing a team-high 40 minutes.

But the injury limited Tatum’s participation in Tuesday’s Celtics practice, according to head coach Joe Mazzulla, who described the four-time All-NBA wing’s status as “day to day.”

“He was able to do some stuff,” Mazzulla said. “He was sore after the game. He’s gotten a little better today. He was able to do through some on-court work and go from there.”

Tatum typically sticks around for extra work after practice, but he was not part of that group Tuesday. The group included the likes of Jaylen Brown, Derrick White and Kristaps Porzingis. Later in the day, ESPN’s Shams Charania reported Tatum underwent an MRI and was diagnosed with a bone bruise, which Charania referred to as a “pain tolerance injury.”

Tatum led the Celtics in points, rebounds and assists per game this season and finished tied for 13th in the NBA in total minutes played. He also led Boston in all four categories during last year’s playoff run, averaging 40.4 minutes per game.

The Celtics have played 114 postseason games since Tatum entered the NBA in 2017, and he’s logged at least 19 minutes in all of them. Boston went 8-2 in games Tatum missed this season, with both losses coming at Orlando (including one in which Mazzulla sat his entire starting lineup).

In a post-practice news conference, veteran big man Al Horford took issue with the foul that injured Tatum, saying Caldwell-Pope’s aggressive foul crossed a line. Orlando committed the fifth-most fouls in the NBA during the regular season and is known for its physical style of defense.

“Yes, there was something extra,” Horford said. “It was about the second or third time that he, especially KCP, went at him in that way. So, yeah.”

Tatum struggled as a shooter in Game 1 (8-for-22, 1-for-8 from 3-point range, 0-for-4 on free throws) but was otherwise effective, finishing with 17 points, 14 rebounds, four assists, one steal and one block. The Celtics outscored the Magic by 23 points with him on the floor.

Losing Tatum for Game 2 would put more pressure on players like Brown (16 points on 6-for-14 shooting) and Porzingis (five points on 1-for-8 shooting), who both had quiet scoring efforts on Sunday. Brown did look more comfortable and assertive in his return from a lingering knee injury, and Mazzulla said the All-Star did not suffer any setbacks. White and Payton Pritchard combined for 49 points to spearhead Boston’s offense in the series opener.

“No matter what a hard foul is, we’re just going to get up and play ball and just check it back up,” Pritchard said, adding that he isn’t intimidated by Orlando’s physicality. “Obviously, they fouled (Tatum) hard and then he had a little fall, but it’s not going to stop us from what we’re trying to achieve. It’s not going to knock us off our path.”

As for the idea that less talented teams, like the seventh-seeded Magic, can limit the Celtics’ offensive firepower by roughing them up, Pritchard said they’re welcome to try.

“It’s fine, they can try it. See if it works,” he said. “We go into the game and do what we do.”

Pritchard wins Sixth Man

Two years ago, Pritchard was so frustrated with his Celtics role that he requested a trade.

Now, he’s both a vital member of a championship-winning roster and, in the eyes of NBA awards voters, the best bench player in the league.

Pritchard was recognized Tuesday as the NBA’s Sixth Man of the Year for the 2024-25 season, beating out fellow finalists Malik Beasley and Ty Jerome.

The announcement was unsurprising, as the 27-year-old guard had long been viewed as the favorite for the award. Pritchard led the NBA in points (1,079) and plus/minus (plus-428) off the bench during the regular season while also ranking in the top 10 among reserves in assists (third), steals (T-sixth) and offensive rebounds (10th).

The Sixth Man of the Year receives the John Havlicek Trophy, named after the Celtics legend.

Pritchard became the fourth Boston player to win the award, joining Kevin McHale (1983-84, ’84-85), Bill Walton (1985-86) and Malcolm Brogdon (2022-23). Fittingly, it was Brodgon’s 2023 departure that allowed Pritchard to cement himself as a core member of head coach Joe Mazzulla’s rotation.

After Boston traded Brodgon and starting guard Marcus Smart in franchise-altering deals for Jrue Holiday and Porzingis, Pritchard went from appearing in 48 games in 2022-23 to all 82 last season. He posted career highs in most statistical categories, including points, assists, rebounds and minutes per game, and hit one of the biggest shots of the Celtics’ championship run: a halftime buzzer-beater from beyond halfcourt in the NBA Finals clincher against Dallas.

Pritchard then improved in all of those metrics this season, emerging as not just the NBA’s most productive bench player, but also one of its most dangerous perimeter shooters, full stop.

Only Anthony Edwards, Beasley, Stephen Curry and White made more 3-pointers than Pritchard’s 255, and of the 39 players who attempted at least 450 threes, just three made them at a higher rate than his 40.7%. Pritchard’s 62.0% effective field-goal percentage and 63.3% true shooting percentage were the best of his career by wide margins, and both ranked in the top 10 among qualified guards.

Boston’s smallest rotation player at 6-foot-1, 195 pounds, Pritchard credited the growth of his game to his work ethic, which included hours of 1-on-1 drills during the Celtics’ offseason.

“I just don’t think you can accomplish anything at the highest of levels unless you give it your all,” he said Tuesday. “… I remember there was a Steve Nash quote and he was like, ‘I wouldn’t be in the position I am today if guys worked as hard as (I) did.’ He’s a little, 6-foot-2 white person, whatever, probably shouldn’t be what he was, but he outworked everybody. There’s people with a lot more gifts that are less like hardworking people, so that’s a pet peeve of mine. And that’s what I strive to be: the hardest worker.”

The Oregon product hit six or more 3-pointers in nine games this season (tied for fifth-most in the league), including a 10-for-16, 43-point, 10-rebound, five-assist tour de force in a March 6 win over the Portland Trail Blazers.

Horford pointed to the Portland game, in which Pritchard fell one 3-pointer shy of the Celtics’ single-game franchise record, as an example of his unselfishness and team-first attitude. He also echoed Mazzulla’s frequent praise for Pritchard’s improved on-ball defense and well-rounded play, and he had no qualms about congratulating his teammate hours before the award was announced.

“I don’t think it’s any secret,” Horford said. “I don’t want to jump the gun, but I’m just very happy for Payton.”
