The September 19 rematch between boxing legends Floyd Mayweather and Manny Pacquiao is “still on” despite Mayweather’s apparent “breach of contract” following his recent comments about the planned Las Vegas fight.

During a meeting at Caesar’s Palace last Saturday, Mayweather told Vegas Sports Today, “we don’t know where the fight is. The sphere is one of the places they talked about. So we don’t know if he’ll be there 100 percent. And it’s not actually a fight. It’s an exhibition.”

Jas Mathur, CEO of Manny Pacquiao Promotions and producer of the event, objected to Mayweather’s comments, telling ESPN on Wednesday that the undefeated fighter’s statements were contrary to their contract.

“Right now, the fight is still going on. There is no conclusion and he has signed a contract to fight professionally,” Mathur said. “Floyd Mayweather is officially in breach of his contract. He has been in breach of his contract since the day he came out and said what he said on Saturday, and he has been in official breach of his contract since yesterday.”

Mathur told ESPN he has been in talks with Mayweather’s team since the boxer’s comments Saturday, with Team Mayweather insisting that the fight be changed from a sanctioned professional fight to an exhibition fight, one of several contract violations.

Mathur suggested that Mayweather also knew about a recent visit to The Sphere, which was attended by 35-40 representatives from Manny Pacquiao Promotions, Mayweather Promotions and Netflix, as well as producers Hidden Empires, EverWonder Studios and Limitless X Holdings.

Mayweather’s proposed June exhibition with Greek kickboxer Mike Zambidis also directly violates his contract to fight Pacquiao, according to Mathur, who added that there is a cure period during which Mayweather can cure the violation after receiving written notice of the violation.

Mathur also stated that Mayweather has already taken a down payment on his fight purse.

“Floyd Mayweather signed not one, not two, but three different contracts on three different dates with two different parties that ultimately came together in January,” Mathur said. “And it all has to do with his return to professional boxing. The first one was on October 24. The second one was on November 6. The third one was on December 14. When he signed them, he received money for all three contracts. Moreover, he also took an advance payment towards his purse for the fight with Pacquiao.”

The Mayweather-Pacquiao 2 fight was announced in February as a professional boxing fight, just days after Mayweather announced he was coming out of retirement during an event organized for The Sphere and which will be streamed worldwide on Netflix.

The fight was to be, as Mathur put it, “boxing’s first-ever sports and entertainment event,” a spectacle that would leverage the technology of a $2.3 billion entertainment venue.

“No one in the last three months has mentioned anything related to the venue or that the fight is not a professional fight,” Mathur said. “His team had all the contracts. He signed all the contracts. We have DocuSign evidence, as well as damp signatures with the device ID, IP address and everything that’s in there.”

Ultimately, there will be a stalemate as Mathur said Manny Pacquiao will not budge on turning the fight into an exhibition because of his steadfast desire to avenge his 2015 loss to Mayweather.

“If he’s afraid of Manny and doesn’t want to jeopardize his professional boxing record, not only should he never sign one of these contracts, but he should just come out and say it because Manny is not afraid,” Mathur said.

“We put it together to create something that the fans would love and that would be a huge sporting event. We wanted to do something that would make history, and he wants to come in and try to change the terms at the last minute because he thinks he can. No, he can’t. It’s not happening.”
