The UFC Featherweight Champion made the proposal on Instagram after the former boxer, who retired last year without ever losing a bout, claimed McGregor received preferential treatment in the media due to his skin colour.
During a interview with Fight Hype last week, Mayweather stated that “racism still exists in combat sports.”
He continued: “What’s so crazy, I don’t really know the McGregor guy; never seen him fight, I heard his name actually from one of the runners that works for our company.
“He told me about the guy McGregor. They say he talk a lot of trash and people praise him for it, but when I did it, they say I’m cocky and arrogant.
“So biased! Like I said before, all I’m saying is this, I ain’t racist at all, but I’m telling you racism still exists.”
McGregor responded by posting: “Do not ever put me in a bracket like this again.
“I am an Irishman. My people have been oppressed our entire existence. And still very much are. I understand the feeling of prejudice. It is a feeling that is deep in my blood.
“In my family’s long history of warfare there was a time where just having the name ‘McGregor’ was punishable by death.
“I will give you a fair 80/20 split purse in my favour seen as your last fight bombed at every area of revenue.
“At 27 years of age I now hold the key to this game, the game answers to me now.”
The combatants exchanged words last year when ‘The Celtic Tiger’ said he would “kill” Mayweather “in less than 30 seconds” if they ever fought.
‘Money May’ replied by saying he “didn’t take McGregor seriously.”
McGregor also apologised for posting a image of him pointing a gun at the camera, explaining that he was “simply rehearsing for a potential upcoming film role.”
Does Mayweather have a fair point about how the media presents him?
Who would you back in a fight between the two?
