Jayson Tatum dunked on LeBron James during the Boston Celtics’ 123-101 rout of the Philadelphia 76ers on Tuesday night, bringing back memories of a moment from eight years earlier and sparking plenty of reaction online.

The game also carried another storyline for the six-time All-Star, who was facing Jaylen Brown for the first time since his longtime Celtics teammate was traded to Philadelphia.

The dunk came with 6:06 left in the third quarter, one possession after Tatum blocked VJ Edgecombe’s layup and grabbed the rebound. He then worked through a double team before throwing down a one-handed rim-rattling slam over James to push Boston’s lead to 73-67.

“It just kind of felt good to finish through contact. It’s been about 19 months since I dunked on somebody. Just to kind of get my legs back, feeling good, it’s a basketball play,” the 28-year-old said after the game.

By Wednesday morning, the Celtics had summed up the play in two words: “Zero gravity.”

“Pardon My Take” had its own description: “Tatum puts LeBron on LePoster.”

The dunk also immediately drew comparisons to Tatum’s rookie season, when he threw one down over the four-time NBA MVP in Game 7 of the 2018 Eastern Conference finals.

“Tatum turned back the clock on LeBron,” SportsCenter wrote.

Barstool Sports Celtics analyst Dan Greenberg added: “Time is a flat circle.”

The attention then shifted to Brown, whose first meeting with his former teammate had already drawn interest before tipoff.

After the dunk, Brick Center reacted: “Tatum dunked on LeBron. The camera IMMEDIATELY cut to Jaylen Brown.”

NBA/NFL insider Matt Wallace also highlighted their pregame interaction.

“Jayson Tatum walked over before tip-off tonight to show love to his old teammate Jaylen Brown. Tapped his arm, tapped his chest, nothing but respect. Brown looked right through him. Wouldn’t even acknowledge him. Just kept spinning the ball like Tatum didn’t exist. Tatum took the high road and let it go,” Wallace noted.

The 2024 NBA Finals MVP later said he had not been focused on the exchange.

“I’m just focused on coming out and doing what’s best for my team. Everything else was just, to be honest, I wasn’t paying attention. But credit to Jayson. He played well tonight,” Brown said.

Brown finished with 13 points on 4-for-9 shooting in 26 minutes, along with 4 turnovers and a game-worst minus-27.

Asked about the same pregame moment, Tatum dismissed the idea that there was anything more to it.

“Like I said, there are no headlines about anything like that. I was just getting ready for the game, ready for jump ball, go out there, compete, have some fun, and try to get a win,” he said.

The Boston forward finished with 21 points on 8-for-17 shooting, 6 rebounds, 4 assists and 2 blocks in 32 minutes.

One fan put it simply: “Jayson Tatum handled his business against the 76ers.”

Boston improved to 9-2 with the win, while Paul George led all scorers with 36 points against the team that traded him.

Tatum and Brown are scheduled to meet again on Jan. 21, when the 76ers visit TD Garden for the teams’ first regular-season matchup in Boston since the trade.
