This past week has seen a swirl of rumors saying that the unprecedented fight between UFC lightweight champion Conor McGregor and undefeated boxer Floyd Mayweather Jr. was close to being a reality. UFC featherweight champion Jose Aldo recently weighed in on the prospected super fight, saying that it “will never happen.”

“It will never happen,” Jose Aldo told Omnisport. This will only happen if the UFC wants to do it.” The Brazilian, who was knocked out by Conor McGregor in 13 seconds in 2015, added that no fighter under contract with the UFC can go over the company. During a pay-per-view interview event, Conor McGregor said that he will make the fight with Floyd Mayweather happen with or without the UFC. Jose Aldo is scheduled to fight interim featherweight champion Max Holloway at UFC 212 on June 3.

On Tuesday, The Irish Sun reported that the camps of Conor McGregor and Floyd Mayweather have agreed to terms for the prospective billion dollar fight. Shortly after the report sent shockwaves to the sporting world, though, both Mayweather and UFC president Dana White denied the report that a deal has been reached.

Floyd Mayweather has been sending mixed messages regarding the potential fight with Conor McGregor. He recently said that the two camps were “very close” to reaching an agreement. He also tweeted at McGregor saying that if the Irishman really wants to make the fight happen, he should take care of his business with the UFC before getting in touch with his people.

Boxing promoter Eddie Hearn also weighed in on the potential Conor McGregor – Floyd Mayweather boxing match saying it will be a “complete disaster,” according to Bleacher Report. He did clarify that pitting together such outsized personalities would be a huge spectacle to the ordinary man on the street, while pointing out that to an educated boxing fan, it would be a terrible fight. Hearn also said that if they need a promoter, he’s willing to do it.
