Floyd Mayweather is facing a new legal challenge after promoter CSI Entertainment filed a lawsuit seeking repayment of $4.65 million in advances allegedly paid to the boxing legend for two fights that never materialized.
TMZ Sports reported Thursday that CSI Entertainment filed the lawsuit in New York, alleging it paid millions of dollars for exclusive rights to exhibition bouts involving Mike Tyson and Manny Pacquiao.
CSI claims it paid $4.5 million in advances to Mayweather’s management company, First Apex Ventures, for the proposed events. The company alleges the agreements gave it exclusive rights to promote the fights and says Mayweather personally approved the deals.
Court filings allege that CSI later discovered plans for Mayweather to move forward with other promotional partners for separate events involving Mike Zambidis and Pacquiao despite the company’s claimed exclusive rights. The lawsuit seeks an injunction that would prevent Mayweather from participating in his June 27 exhibition against Zambidis in Athens, Greece, while the dispute is being litigated.
The proposed Tyson and Pacquiao matchups were among the highest-profile exhibition concepts discussed in recent years. Neither fight took place, leading CSI to seek repayment of the money it says was advanced under the agreements.
The lawsuit comes while Mayweather is pursuing separate litigation against Frist Apex Ventures and his former manager. In that case, Mayweather is seeking $175 million in damages and alleges he was defrauded by individuals involved in his business affairs.
Neither Mayweather nor representatives of his management company had publicly responded to the allegations at the time of publication.
