​Promoter CSI Entertainment is planning to stage an exhibition boxing match between Floyd Mayweather and Mike Tyson on September 26 at the American Airlines Center in Dallas, according to a new court filing. The event had been initially targeted for May 30, but an injury to Tyson, who is 60 years old, forced the postponement. Under the terms of the agreement, CSI had a six-month window from May 30 to reschedule the exhibition and now aims to hold the bout at the end of September.
Mayweather, now 49, was sued last month in federal court in New York by CSI, which alleges that the Hall of Fame boxer received $4.65 million in advances to fight Tyson and Manny Pacquiao, only to back out of the deal. CSI asked the court to grant an injunction that would prevent Mayweather from facing Mike Zambidis in a planned June 27 exhibition and to stop him from taking any fight other than against Tyson next, with CSI’s approval, and for Mayweather to fight Pacquiao—or another CSI-approved opponent—immediately after Tyson.
By the time fight week arrived for the Mayweather vs. Zambidis event, the legal dispute remained unresolved. After DAZN and Ticketmaster were served with notices, the event was ultimately canceled. Last week, U.S. District Judge Vernon S. Broderick denied CSI’s request for a temporary restraining order, finding that the company had not demonstrated irreparable harm, but left CSI’s request for a preliminary injunction pending. Broderick then instructed the parties to meet and confer to establish a schedule for discovery and briefing on CSI’s request for a preliminary injunction. Unable to reach an agreement, CSI’s and Mayweather’s legal teams each submitted separate proposals to the court.
In a letter sent Thursday to Judge Broderick, CSI attorney Judd Burstein urged expedited proceedings on the company’s request for a preliminary injunction against Mayweather, arguing that a quicker ruling is essential if the September 26 event is to be staged. The letter noted that Mayweather’s exhibition match against kickboxer Mike Zambidis was canceled in June, and it laid out the timetable CSI believes is necessary to keep the Tyson fight on track.
Burstein wrote, “First, Plaintiffs believe that a preliminary injunction hearing will require two to three days of testimony and request that the Court schedule the hearing on August 26 to 28, 2026 — dates on which David Jonelis, lead counsel for Defendant Floyd Mayweather Jr. (‘Mayweather’), has told me that he is available.” He added that CSI intends to proceed with the “Tyson Fight” on September 26, 2026 if Mr. Mayweather agrees to participate. To that end, CSI has the American Airlines Center in Dallas “on hold”; Tyson is willing and able to fight on that date; and CSI will either secure the required promoter’s license or retain a licensed promoter to promote the fight.
CSI argues that the expedited hearing is necessary to keep the September date viable, and observers note that a delay in the hearing could jeopardize the potential September showdown. The core dispute centers on whether CSI has a viable path to secure the event, secure the necessary licensing, and obtain Mayweather’s participation, given the ongoing litigation and the unresolved injunction request. The court has yet to establish a schedule for discovery and trial on the preliminary injunction.
As this case moves forward, the prospect of a Tyson versus Mayweather exhibition on September 26 in Dallas remains contingent on the court’s rulings, Mayweather’s agreement to participate, and CSI’s ability to secure the requisite promotional permissions. If successful, the event would mark a high-profile return to the exhibition boxing format, reigniting discussions about celebrity fights and the business dynamics that surround them. If not, CSI may need to reassess its plans and potential opponents, while Mayweather and Tyson’s schedules and contractual relationships continue to be scrutinized in court.
