Floyd Mayweather is facing a new legal dispute after a boxing promoter filed a lawsuit seeking $4.65 million linked to two major fights that never happened. The lawsuit, filed in New York federal court by CSI Sports Events, claims Mayweather breached an exclusive promotional agreement tied to a planned exhibition bout with Mike Tyson and a professional rematch with Manny Pacquiao.
The case centers on millions of dollars in advance payments made to secure promotional rights for the events. CSI is now seeking repayment of those funds and wants to stop Mayweather’s upcoming exhibition fight in Greece. The lawsuit has drawn renewed attention to several high-profile boxing projects that were announced but never reached the ring, creating uncertainty around Mayweather’s exhibition schedule.
Floyd Mayweather Lawsuit Seeks Recovery of $4.65 Million
The Floyd Mayweather lawsuit was filed on June 18 in federal court in New York. According to the complaint, CSI Sports Events paid Mayweather’s management company, First Apex Ventures, a $4.5 million advance in exchange for exclusive rights to promote several boxing events involving the former world champion.
The agreement reportedly included an exhibition fight against Mike Tyson and a professional rematch with Manny Pacquiao. CSI also paid an additional $150,000 for medical examinations connected to the planned Tyson exhibition. The promoter is now seeking a total of $4.65 million in damages.
The lawsuit claims the contract granted CSI exclusive promotional rights and prohibited Mayweather from participating in other boxing events until he fulfilled his obligations under the Tyson agreement. CSI argues that those terms were violated and is asking the court to recover its investment.
Mike Tyson’s fight plans fell apart after an injury
The proposed Mike Tyson exhibition was expected to take place in spring 2026. Earlier reports linked the event to a possible April date in the Democratic Republic of Congo. Mayweather was reportedly set to earn $14 million for the fight, with part of that amount already advanced through the broader agreement.
According to the complaint, Tyson suffered a hand injury that prevented him from meeting a May 30 contractual deadline. The agreement reportedly allowed an interim fight only if Tyson remained unavailable after November 30.
CSI alleges that Mayweather announced a separate exhibition against Greek kickboxer Mike “Iron” Zambidis just one day after receiving the $150,000 medical advance payment. The promoter claims this action violated the terms of the exclusive promotional deal tied to the Tyson event.
The dispute over the Tyson fight forms a major part of the Floyd Mayweather lawsuit and could play a key role as the case moves through federal court.
Manny Pacquiao Rematch and Greece Event Face Questions
The lawsuit also addresses a planned Manny Pacquiao rematch. CSI claims Mayweather entered into a separate agreement with production company Everwonder for a fight that was expected to stream on Netflix from The Sphere in Las Vegas.
The complaint states that the Pacquiao project included a significant advance payment before the deal was later settled. CSI says it was removed as Mayweather’s promoter during settlement discussions.
Mayweather defeated Pacquiao in their record-setting 2015 fight, but a rematch has never taken place despite years of discussions and public announcements.
Meanwhile, Mayweather remains scheduled to face Mike Zambidis in an exhibition on June 27 in Athens. The event at the Telekom Center inside the OAKA Olympic Complex is being promoted by Mayweather Promotions in association with Zambidis Club and will be broadcast on DAZN. Some ticketing platforms reportedly paused sales after news of the legal dispute emerged.
CSI is asking the court to block the Greece event while the Floyd Mayweather lawsuit proceeds. The company is seeking both financial damages and injunctive relief. No response from Mayweather’s representatives was immediately available at the time of reporting. The case is expected to continue through the federal court system in the coming weeks. The outcome could affect the Athens exhibition and any future plans involving a potential Pacquiao rematch.
