Former Celtics star Jaylen Brown said he’s excited, but unemotional as he prepares to face his old team for the first time.

Brown and the 76ers will host Boston on Tuesday at Xfinity Mobile Arena. It’s the first regular-season meeting between the 2024 NBA Finals MVP and the club that drafted him in 2016.

“I think it should be fun,” Brown told reporters Sunday in Chicago. “(It’s) a good opportunity for our team to be able to show what we’re made of, so I’m looking forward to it. A big-time matchup, two heavyweights in the East. Let’s get it.”

Brown spent the first decade of his career in Boston, winning one championship and scoring the 10th-most points in franchise history. His final season with the Celtics — during which he posted career-best numbers and made second-team All-NBA — ended with a postseason loss to the 76ers, followed by a stunning offseason trade to Philly two months later.

The Celtics and Sixers matched up twice during the preseason, with Brown playing in one of those games and traveling to TD Garden for the other. He was asked whether those exhibitions would ease his emotions Tuesday night.

“We’ll see how we feel when we get out there, but as of now, I’ve got no emotion towards nothing,” he replied. “I’m just ready to go.”

Brown said in July that he felt disrespected by the trade, which Celtics president of basketball operations Brad Stevens said was driven by a desire to no longer have two high-usage superstars accounting for 70% of Boston’s salary cap.

More recently, Brown has taken aim at his former co-star, Jayson Tatum. He called Tatum’s claim that he was surprised by Brown’s trade to Philly “cap” (aka untruthful) and later said the two have, if not a full-fledged “beef,” “a little lamb chops and gravy.” Brown also said Tatum “should stay ready at all times.”

When the Celtics and 76ers played in Boston on Oct. 10, Brown and Tatum warmed up feet from each other without interacting. Brown said he does not plan to speak with his former teammate before Tuesday’s game, either.

“There’s nothing to talk about,” Brown told reporters Sunday. “He’s on his side; I’m on my side. We’re playing basketball. Both of us are trying to win. So there’s nothing to talk about. Just check the ball up.”

Tatum addressed his and Brown’s relationship at length in a postgame news conference on Oct. 23, including saying he would “welcome” a conversation to hash out their differences. Since then, he’s declined to discuss the matter further.

After the Celtics beat the Milwaukee Bucks 117-97 on Sunday to improve to 8-2, Tatum framed Tuesday’s clash as a battle of Atlantic Division rivals, not a showdown between him and Brown. Philadelphia, which also added LeBron James to a roster featuring Tyrese Maxey, Joel Embiid and VJ Edgecombe, owns the best record in the Eastern Conference at 9-2.

“It’s another game on the schedule, and it’s Celtics vs. Sixers,” Tatum told reporters in Milwaukee. “I always say, in the words of Brad Stevens, they all count as one, right? So this one counted as one; we go get ready for Tuesday. It’s a really good team, obviously. Incredible group, great coaching staff. They’ve been playing really well. So from that standpoint, it’s going to be fun, but it’s nothing more than Celtics vs. Sixers.”

Beyond the Brown/Tatum intrigue, the game also will be the first for Paul George against his former team.

George, the unpopular headliner of the Celtics’ return for Brown, is off to a strong start in Boston, averaging 20.4 points per game while thriving as a defensive playmaker. He tallied 27 points on 11-of-18 shooting with two steals in Sunday’s win.

“It’ll be fun,” George said in a postgame interview with NBC Sports Boston’s Abby Chin. “Obviously, great relationships there. It’ll be great to see those guys and compete against them finally. But obviously, Philly was a special place for me. It was a rough tenure, my two years there, but it’ll be special to be in a building.”
