Floyd Mayweather was supposed to return to the ring this weekend (Sat. June 27th, 2026) in Greece to fight former kickboxing champion Mike Zambidis, but a lawsuit from promoters CSI stopped the exhibition fight from going forward.
CSI’s argument: Mayweather had signed contracts with them to fight Mike Tyson next, and already took millions of dollars in advances from them. They filed an injunction to stop Floyd from fighting, and it looks like they were about to win in court when Mayweather’s team
cancelled the fight last-minute.
Mayweather is currently limping through another tough money patch. He’s suing multiple former partners alleging they stole hundreds of millions of dollars from him, and getting into trouble for non-payment, breach of contract, and writing bad checks. No one cared about the Zambidis fight, but it would have given Mayweather some much-needed liquidity to get through this lean stretch.
Following Sunday night’s Zuffa Boxing 08 event, founder Dana White commented on Mayweather’s money issues and suggested perhaps Zuffa could work with him.
“I’ve talked to [Mayweather] about it but I don’t know enough about it,” White said. “You hear all these different stories, and I think you have to wait to see how this thing is going to play out in court for him. But when somebody works as hard as he did and amasses the type of wealth that he had and then they lose it, or it gets stolen or whatever the deal is, it’s horrible and it happens a lot in professional sports.”
“So who knows? Anything is possible and maybe we could do something to figure it out for him.”
For now, it seems Floyd Mayweather is tightly locked into the deal he signed with CSI. That’s not exactly a terrible place to be. They want him to box Mike Tyson in September and Manny Pacquiao sometime in 2027. Those fights may be way past their best before date, but they’ll still generate interest and lots of money. If Mayweather can stop trying to shoot himself in both feet and just go ahead with those bouts, he could be laughing all the way to the bank within 12 months.
Will he actually go ahead with them, though? Or will CSI have to drag him to court again over the millions they’ve already paid him, adding to his growing list of bad debts. Until all of that is sorted, we doubt Zuffa Boxing is going to get involved — unless their Saudi partners are willing to throw a bunch of cash into the “Money” pit and roll the dice.
