Mike Tyson threatened to start his fight with Jake Paul one day before the match, after he slapped him during their last confrontation.
The heavyweight legend returns to the ring for a controversial bout against YouTuber turned boxer Paul in Texas.
Tyson looked in sensational shape as he stepped on the scales at 228.4lb (16 3lb) while wearing a pair of Versace trousers.
That was before Paul came in at the heaviest weight of his career at 227.2 pounds (16 lbs) almost two stone above his usual fighting weight.
The two faced off for the final time but Tyson delivered a slap to Paul – before the tricky fighter could get any closer.
This sparked an almost brawl on stage, as the two camps and security intervened and separated the couple.
Paul, 27, roared unconvincingly while his entourage calmed Tyson, 58, before sending a final warning.
He said: The talk is over.
The last time Tyson was in the ring was in 2020 for an exhibition bout with Roy Jones Jr., which proved to be nothing more than a glorified bout.
His career officially came to a frustrating end in 2005 when he resigned from his chair and threw in the towel on his boxing career.

But he returns to face Paul – more than 30 years his junior – in what will be Netflix's first foray into live boxing.
The fight is scheduled to take place in eight two-minute rounds — versus the usual three — with larger gloves weighing 14 ounces versus 10 ounces.
But the gloves were off on Thursday just 24 hours after fight night – with Paul laughing at Iron Mike's power.
“I didn't even feel it. He's angry, he's an angry little elf,” he told host Ariel Helwani.
“Mike Tyson, I thought that was a nice friend but you're going to get fired tomorrow.
“I'm fucking him, Ariel. I'm fucking him. He's hitting like a father***h! It's personal now, it's personal now. He should die.”
