A teen was beaten into a coma by a brute bellowing “Spurs in 7” during a livestreamed Midtown brawl as Game 4 of the NBA finals neared its triumphant end for the Knicks, cops and sources said. 

Johnny Aumuller, 17, was knocked around by a crew that included a rabble-rouser in a black-and-white striped shirt around 11:45 p.m. Wednesday at West 35th Street near Eighth Avenue — a short walk from Madison Square Garden, law enforcement sources said.

“I have no words for him,” Johnny’s mother, Shiomara Arce, told The Post Friday. “Right now my son comes first. This person needs to pay for what he’s done.”

The teen victim was part of a group that gathered to watch the game when the aggressor declared, “Spurs are up right now. We’re winning. Spurs in 7,” according to the sources.

That set off a Knicks fan in the crowd, who snapped back, “F–k the Spurs. Suck my d–k,” the sources said.

While the teen victim was not the one who made that comment, he was with the Knicks fan’s crew — and a violent brawl erupted in which he soon became the target, the sources said.

Johnny was pummeled by a ruthless mob, before the initial Spurs fan picked him up and threw him on the ground, according to the sources.

The badly battered teen, who sources say divides his time between the Bronx and Connecticut, suffered a seizure and went into a coma, cops said.

He was rushed to Bellevue Hospital, where he eventually came out of the coma and was listed in critical but stable condition, cops and sources said. 

Arce told The Post Friday her son should be moved out of the ICU soon.

“He’s pulling through. He is responding,” Arce said. “The doctor said they will take him off the ventilator today. Hopefully he will be in a regular room tomorrow.”

When he is released, Arce said, she will make sure he doesn’t venture into the city for future games. 

“I don’t want him at Madison Square Garden,” she said. “He can watch it on TV.”

She described Johnny as “a Knicks fan” who is “always playing basketball in the neighborhood.” 

He went to a watch party Wednesday night, but from there, had no contact with his family “all night,” she added. 

The entire violent ordeal was streamed on the PRISM app – but Arce said she 

“can’t bring [her]self to watch that.”

The video shows a handful of onlookers saying, “Wait, wait, chill, chill” as the violence heated up in front of a food cart.

“I should’ve killed this n—a, right? I should’ve f—ked this n–a up,” the initial aggressor could be heard saying, apparently referring to the Knicks fan who first snapped back at him.

Dozens of bystanders either filmed and did nothing, or were too engrossed in the final tense moments of the game to get involved.

But others seemed to have been distracted by the brawl and missed the Knicks’ historic 107-106 comeback win, until a roar went up in the crowd.

“What’s the score? What happened?” people could be heard saying. 

Police were still looking for the black-and-white-clad attacker and released his photo. 

Madison Square Garden canceled a planned Knicks watch party outside the arena hours before Game 4 — as owner James Dolan said neither Mayor Zohran Mamdani nor NYPD Commissioner Tisch was experienced enough to handle the major event.

The parties have been raucous during the Knicks’ magical playoff run, but at times some fans have turned unruly and even violent, leading to arrests.

After Game 3, a rowdy mob pummeled a Spurs fan and snatched his jersey in a viral caught-on-camera beatdown, cops said.

No one has been arrested in that brutal mugging. 

Post-Game 4 shenanigans included a wild mob — with at least one in blue and orange Knicks merch — launching chairs at a Midtown Five Guys employee, leaving him bloodied.
