Two years ago during the NBA playoffs, Knicks fans took over Wells Fargo Center to the point that it felt like “Madison Square Garden South" to the 76ers.

With the teams poised to renew acquaintances in the Eastern Conference semifinals beginning Monday, Joel Embiid does not want history to repeat itself after the Knicks won that dramatic 2024 series in six games.

The Sixers’ star warned fans not to sell their tickets and even offered to pay for them to insure a homecourt atmosphere for games at the arena, now called Xfinity Mobile Arena.

“I have a message for our fans," Embiid said after putting up 34 points, 12 rebounds and 6 assists as the 76ers completed a comeback from 3-1 down to beat the Boston Celtics, 109-100, in Game 7 at TD Garden. "Last time we played the Knicks, it felt like (Philly) was Madison Square Garden East. We’re gonna need the support.

"Don’t sell your tickets. This is bigger than you. We need you guys. The atmosphere you guys created in the last two games, especially in (Game 6), we need all of it. Knicks fans travel; they buy tickets. There’s gonna be people who will sell the tickets because they need the money. Don’t do it, we need you guys. We need the support, and we need them to be extremely loud. If you need money, I’ve got you.”

The Sixers, meantime, are officially trying to restrict ticket sales to prevent Knicks fans from buying them, a practice that is not uncommon in pro sports.

“Sales to this event will be restricted to residents of Greater Philadelphia area," the team announced. “Residency will be based on credit card billing address. Orders by residents outside area will be canceled without notice and refunds given.”

The No. 3 Knicks will have homecourt advantage against the No. 7 Sixers, with Games 1 (Monday) and 2 (Wednesday) at Madison Square Garden and Games 3 (Friday) and 4 (Sunday) in Philadelphia.

A potential Game 7 would be May 17 at the Garden.

Embiid had been 0-3 in Game 7s in his career, but said before Game 7 against the Celtics he was “tired of losing” to them.

“I’ve been playing these guys for so long,” Embiid said. “I’m tired of losing to them. So we have a chance to accomplish something special. They’re a great team. You look at everything they have. That’s a super team. We just gotta go in with the mindset that we’ve had for the last two games. One play at a time. Tough environment, but we’ve been there. We won two games over there.”

With Jayson Tatum (left knee injury) a late scratch, the 76ers became the first No. 7 seed in the East to defeat a No. 2 seed since the first round expanded to best-of-seven in 2003. They are also the 14th team in NBA history to overcome a 3-1 deficit to win a series.

Now comes a rematch with the Knicks, with a berth in the Eastern Conference Finals on the line.

The teams split the season series 2-2.

In the 2024 playoffs, Knicks fans took over Wells Fargo and dominated the arena.

In Game 4, Knicks fans who made the two-hour drive down I-95 chanted “MVP” as Jalen Brunson poured in a franchise-record 47 points with 10 assists in a 97-92 victory.

They chanted “F--- Embiid” at the Sixers’ star and poured out into the concourses after the game and chanted “Knicks in five!”

“They’re for real,” Jalen Brunson told reporters of the fans. “No matter where we are, they’re gonna be there. So I’m appreciative and a lot of situations (this season) wouldn’t be done without them.”

Embiid wasn’t happy about it.

“Disappointing. I love our fans,” Embiid told reporters. “Think it’s unfortunate and I’m not calling them out, but it is disappointing.

“Obviously you got a lot of Knicks fans and they’re down the road and I’ve never seen it, and I’ve been here for 10 years. Yeah, it kind of pisses me off, especially because Philly is considered a sports town. They’ve always shown up and I don’t think that should happen. Yeah. It’s not okay.”

In 2024, Tyrese Maxey saved the Sixers from elimination in Game 5 at the Garden with a 46-point outing. But the Knicks closed out Game 6 on the road behind Brunson’s 41 points and 12 assists

After the series-clinching win, Knicks fans crowded near New York’s tunnel after the game and held their phones high to capture video of their favorite team headed to the locker room.

“Was it hostile?” then-Knicks coach Tom Thibodeau joked when asked about the atmosphere.

With the teams set to meet again starting this week, Embiid is doing all he can to avoid a hostile crowd on his homecourt.
