Mike Tyson slapped Jake Paul at a charged weigh-in for Friday's controversial heavyweight fight in Texas.
Novice boxer Paul, 27, will take on 58-year-old Tyson at the AT&T Stadium in Dallas.
After both men had weighed in, Paul crawled across the floor before rising up to Tyson's eyeline for the traditional final head-to-head.
Tyson had refused to engage with Paul's goading for much of fight week, but slapped his opponent across the face, prompting security and team members to rush in to separate the fighters.
"Talking's over," Tyson said and walked off stage. Paul, meanwhile, was smiling before sitting down and appearing to meditate.
"I didn't even feel it. He's angry. He's an angry little elf," Paul said of the slap.
"Mike Tyson, I thought that was a cute slap, buddy, but tomorrow you're getting knocked out."
Two-time world champion Tyson – who last completed professionally in 2005 - had just weighed in at 16st 4lb with Paul a pound lighter.
