Jake Paul has been warned that he will be put in a neck brace if he pulls another stunt with Floyd Mayweather.
The pair were engaged in a violent altercation at the launch press conference for Mayweather's fight with YouTube star Logan, which resulted in Paul taking a punch from the boxing veteran.
And Mayweather has claimed that the punishment will be much more severe should Jake attempt anything similar in the build-up to his exhibition bout in Miami on Sunday.
"I'm nothing to play with," Floyd told Showtime. "I ain't one for the jokes, that's why you [Jake Paul] ended up with two black eyes.
"That was totally disrespectful, your nose got f***ed up and your teeth got chipped - keep f***ing with me and next time you're going to end up in a neck brace."
As Mayweather was doing media interviews in the tunnel area at the Hard Rock Stadium, Jake Paul approached him and the pair engaged in a war of words, with the boxing legend declaring he would beat both Paul brothers in one night.
But things became physical when Paul snatched Mayweather's cap, sparking a brawl which left the YouTube star with a black eye.
And despite early indications that he would be banned from attending his brother's fight due to his actions, it appears that Jake will now be allowed to attend the exhibition.
The bout will take place over eight three minute rounds, and due to exhibition rules Paul will be allowed to weigh in at 190lbs; 30lbs heavier than Mayweather.
But Paul insists he is not treating the bout as an exhibition and that he is determine to hand Mayweather his first 'loss' since turning professional in 1996.
"It's not an exhibition," he said. "What exhibition is eight three-minute rounds? You know, this is a fight. If Floyd didn't want to rip my head off before my brother took his hat, now he's trying to kill me.
"He's trying to make an example of the big brother so the younger brother has to suffer, watch and witness. I don't know if you've seen Scarface but that's what he's trying to do.
"It's going to be a war, I'm not going to make this s*** easy for him. We've been training our a**es off for eight months now to fight this guy."
It is expected that both men will make millions from the pay-per-view showcase, that also features the debut of NFL star Chad 'Ochocinco' Johnson and a number of high-level professional fights.
Paul, who is 0-1 as a professional, is a huge underdog against 50-0 Mayweather, who has wins over Manny Pacquiao, Saul 'Canelo' Alvarez and Conor McGregor on his resume.
