KSI claimed that in the wake of the Jake Paul vs. Mike Tyson fight, boxing legend Evander Holyfield contacted him to informally set up a fight.
YouTuber-turned-boxer Paul and heavyweight icon Tyson will clash in Texas on July 20th.
And KSI has been one of the harshest critics of the controversial clash, citing their 30-year age difference.
KSI was a guest on Paul's brother Logan's podcast Impaulsive and claimed he had received a message from Holyfield, 61, to organize a fight.
He said, “You know what's funny? Evander Holyfield followed me and messaged me and sent me DMs and I was like, 'No.'
“I don't mean that. I just don't want to be seen as a man. I think that's a low-hanging fruit for me.”
Tyson, 57, officially retired in 2005, but returned in 2020 for an exhibition match against Roy Jones Jr., which ended in an eight-round draw.
Meanwhile, Paul is 9-1 as a boxer, with his only loss coming to 24-year-old Tommy Fury in February 2023, but he has won three times since then.
The exact rules and regulations for the megafight with Tyson, the number of rounds, and whether it will be professionally sanctioned have not yet been announced.
However, Paul's business partner and co-founder of Most Valuable Promotions, Nakisa Bidalian, confirmed that he will not be wearing headgear.

KSI, who had seven fights himself, continued his criticism by adding, “He's going to get the attention of so many people, millions of people.
“Everyone will know him as the guy who knocked out old Mike Tyson.”
Paul, 27, hit back at KSI, 30, on his stream with Adin Ross, writing, “Do you want to know the difference between Mike Tyson and KSI?
“Mike Tyson is actually going to fight me. So who's the bastard now? That's the difference, brother. 'Oh, Mike is this, Mike is 57 years old.'”
“But Mike signed the contract, son of a bitch, KSI. You can say what you want, but you're a fat guy running around doing sidemen YouTube videos and I'm boxing. Change the sport.
