Floyd Mayweather Sued for Alleged Fraud Over Tyson and Pacquiao Fights

Floyd Mayweather Jr. is currently embroiled in a new civil lawsuit filed by CSI Entertainment. The company accuses the renowned boxer of violating multi-million-dollar promotional agreements. These agreements were reportedly tied to significant exhibition matches featuring boxing legends Mike Tyson and Manny Pacquiao.

According to court documents revealed on Thursday, CSI Entertainment asserts that it had advanced approximately $4.65 million. This sum was intended to secure exclusive promotional rights for two major events: an exhibition bout between Mayweather and Tyson, and a rematch with Pacquiao. The plaintiff alleges that Mayweather subsequently jeopardized these agreements by pursuing alternative arrangements without CSI’s involvement.

CSI claims to have initially transferred $4.5 million to Frist Apex Ventures, Mayweather’s management entity. An additional $150,000 was paid shortly before Mayweather announced a separate exhibition fight against kickboxing veteran Mike Zambidis. The promoter contends that this conflicting deal contravened the exclusivity clauses, which stipulated that Mayweather must first fulfill obligations concerning the proposed Tyson matchup.

The lawsuit further alleges that Mayweather entered into separate promotional and streaming agreements for the anticipated Pacquiao rematch. This reportedly included arrangements with other production partners and a planned distribution deal, which CSI claims bypassed their established contractual rights.

CSI Entertainment is seeking the recovery of its advance payments. Additionally, the company is requesting a court injunction to halt Mayweather’s scheduled June 27 exhibition fight against Zambidis in Athens. CSI argues that proceeding with this bout would constitute a further breach of their existing agreement.

This legal filing adds to an increasing number of disputes surrounding Mayweather’s recent exhibition boxing endeavors. These ventures have been characterized by overlapping promotional claims, shifting opponent lineups, and competing broadcast partnerships.

As of Thursday evening, Mayweather has not issued any public statement in response to the lawsuit.
