ORLANDO >> The Celtics had their top duo reunited Friday night in Orlando.

After missing Game 2 of Boston’s first-round playoff series with what head coach Joe Mazzulla called a “severe bone bruise” in his wrist, Jayson Tatum returned to action for Game 3 against the Magic at the Kia Center.

The Celtics initially listed Tatum as doubtful for the game, but he was upgraded to questionable Friday afternoon, then cleared to play shortly before tipoff after going through a pregame warmup. Tatum, who suffered his injury on a hard fall in Game 1, had his shooting wrist taped but did not have any visible limitations in warmups.

“(The injury) was severe enough that he couldn’t play last game,” Mazzulla said pregame. “… He’s had progress. At the end of the day, every day he’s working towards doing whatever he can to put himself in a position to play, and he’ll do whatever he can to do that. He’s done that yesterday and today, and he’s doing a little bit better.”

Also active for Game 3: Jaylen Brown. Brown scored 36 points Wednesday in Tatum’s absence to lead Boston to a 2-0 series lead, but he was added to the injury report after Friday’s morning shootaround. The Celtics listed him as questionable with the right knee posterior impingement that hindered him for the final two months of the regular season, but he also was upgraded to available less than an hour before tip time.

Boston did not have its full starting five available, however. Starting guard Jrue Holiday, whose timely scoring and defensive tenacity against Magic stars Paolo Banchero and Franz Wagner were major assets for the Celtics in Games 1 and 2, was ruled out with a right hamstring strain.

Having to plug lineup holes is nothing new for the Celtics. Their preferred starting five of Tatum, Brown, Holiday, Derrick White and Kristaps Porzingis played just 24 games together during the regular season, including just six after the NBA All-Star break.

“We’ve had to deal with this kind of all season, and because of that, some of our other guys have gotten opportunities,” veteran big man and de facto sixth starter Al Horford said Friday morning. “And it’s no different. Our guys stay ready. We’re preparing for it. Whether it’s Sam Hauser coming off the bench and having an impact, Luke (Kornet), Baylor (Scheierman), whoever it is, we just have to stay ready at any moment. That’s what we did all season, and we’ll see what happens tonight. If that’s what needs to be done, then I know our guys will be ready. And if not, we’ll get rolling like we normally do.”

As they typically do when any starter is unavailable, the Celtics plugged Horford into Holiday’s spot, pairing the 38-year-old with Porzingis in a double-big look.

Game 4 is Sunday night in Orlando. If necessary, Game 5 would be Tuesday back at TD Garden.

Mosley questions calls

The Magic committed the fifth-most fouls in the NBA during the regular season (20.1 per game). The Celtics committed the second-fewest (15.9 per game).

It was not overly surprising, then, to see Orlando, which prides itself on playing a rugged, physical style of basketball, called for more fouls than Boston over the first two games of the series (40-32).

Magic head coach Jamahl Mosley, though, questioned the fairness of the whistle during his pregame news conference Friday, suggesting the officiating has been tilted toward the Celtics.

“You go back and look at the film and you look at the difference in calls,” Mosley said. “The call that Wendell (Carter) gets the foul on Al Horford going to the right, bumps him, Paolo gets the same thing at the end of the quarter, same bump (and doesn’t get the call).”

The Celtics attempted the fewest free throws per game during the regular season — due in large part to their heavy reliance on 3-point shots, which are less likely to draw fouls than drives to the hoop — but they got to the foul line much more frequently in Game 2. Their 33 free-throw attempts in the 109-100 win were their second-most in any game this season, and they outscored the Magic by 10 points on foul shots.

Porzingis accounted for 14 of those Boston free throws (10 makes), including 12 in the first half. The Celtics center only attempted double-digit foul shots once during the regular season: a 13-for-14 showing against Orlando on Dec. 23.

“He’s such a threat,” Mosely said of the 7-foot-3 big man, who tallied 20 points, 10 rebounds, two steals and two blocks in Game 2 and finished the game with five stitches in his forehead after taking an errant elbow from Magic center Goga Bitadze. “The way he spaces the floor at the 3-point line, you’ve got to make sure you get to him. Then you look to switch sometimes, so then it creates that matchup problem, depending on the size that you have on him. And then his unique ability to find a way to get fouled. I think that’s what the biggest problem is: How do you find a way to do all of this without fouling? Because he does a great job of creating that contact. Whether your hands are up or not, he finds a way to rake through those arms.”

Dialing in his shot was a priority for Porzingis entering Game 3. A 41.2% 3-point shooter during the regular season, he went just 6-for-22 from the field and 0-for-7 from three over the first two playoff contests.

“My shot’s still, you know, rushed maybe a few shots,” Porzingis said Wednesday. “I still feel like I have a much higher level to play, offensively especially. I missed a lot. I missed even free throws, I missed a lot of stuff. So I expect myself to be a lot better offensively.”
