Mayweather just watched his Greece exhibition fight get canceled 48 hours before the bell was supposed to ring.
The boxing legend went off at a press conference, saying that a U.S. company called CSI has been actively working to stop the event, and he didn’t hold back his frustration about the whole situation. “I’m very very upset and I’m very very angry that these people are constantly interfering,” Mayweather said, making it clear this wasn’t just business as usual for him. The problem started when CSI Sports Events filed a lawsuit claiming Mayweather violated an exclusive contract worth $4.65 million that locked him into fights with Mike Tyson and Manny Pacquiao instead. According to court documents, CSI filed an emergency injunction request to block the Zambidis exhibition, and the motion remained pending as of June 26, 2026. Mayweather’s attorney, Melissa Glass, told the court that CSI’s legal threats had effectively stopped all promotion and halted ticket sales, making the event commercially unviable.
Floyd Mayweather emphasized his commitment to delivering quality events despite the obstacles, saying his job is to give people the best possible sporting experience and to sell out arenas.
Rather than canceling entirely, Mayweather announced plans to reschedule the exhibition within 30 to 60 days once the CSI situation gets cleared up. He’s currently facing felony charges for writing a bad check to purchase a $200,000 watch in Las Vegas, with charges including theft and intent to defraud. The IRS has also slapped him with a $7.3 million tax lien filed in March 2026 for unpaid taxes dating back to 2018 and 2023.
Meanwhile, Mayweather filed a $175 million lawsuit against his former money manager, Jona Rechnitz, accusing him of stealing through fake investments and unauthorized financial schemes. These mounting legal battles come at a time when Mayweather should be enjoying the twilight of his legendary career, not taking bumps and bruises from courtroom fights.
