The fight, which will be held at the 80,000-capacity home of NFL team the Dallas Cowboys, is a professional contest with a string of conditions.

Paul, 31 years younger than Tyson at age 27, has mostly met ex-UFC fighters, with his solitary defeat coming against British boxer Tommy Fury in February 2023.

He has defended the decision to fight Tyson despite the age difference, saying the hall-of-famer’s experience levels the playing field.

But Hearn – who initiated a defamation case against Paul after the American accused him of bribing boxing judges in October 2022, with a court date reportedly set for this month – disagrees.

“If I was Jake Paul I’d just feel a little bit embarrassed to be honest with you. It’s a liberty,” Hearn said.

“This is dangerous, irresponsible and, in my opinion, disrespectful to the sport of boxing.”

The pair were due to fight on 20 July but Tyson had an ulcer flare-up that forced the match with the YouTuber to be rescheduled.

“That was the moment they should have realised that this was actually a bad idea,” Hearn added.

“Everybody loves a dollar bill, including me, but sometimes the green-eyed monster can make you some bad decisions – and I think this is one of them.”
