Conor McGregor responds to Floyd Mayweather praise, invitation to train: 'F--- the Mayweathers'

Promotion for the upcoming UFC 229 megafight between Conor McGregor and Khabib Nurmagomedov is officially rolling.

And, of course, it’s all calm and reasonable.

Floyd Mayweather sings praises of Conor McGregor

TMZ caught up with Floyd Mayweather on Monday in Atlantic City to get his thoughts on the Oct. 6 clash for the lightweight championship. Mayweather, who faced McGregor in the boxing ring last year, had nothing but kind words for his former opponent and warned Khabib to be ready for a fight.

“I take my hat off to Conor McGregor,” Mayweather said. “A hell of a fighter. …“Conor’s not gonna back down and he’s not a scared fighter at all, win, lose or draw. Conor’s gonna come to fight.”

Mayweather even invited McGregor to train at his gym instead of UFC facilities ahead of the Las Vegas fight. Of course, that seems more a plug than an act of altruism toward McGregor, but it’s a nice offer nonetheless.

McGregor’s bizarre response

McGregor responded to the interview on Twitter Tuesday. The language he used was not friendly.

Um. OK. That seems uncalled for.

Conor’s antics not really a surprise

Of course, uncalled for and unhinged are McGregor’s calling cards. So his response to the man who provided a venue to make tens of millions of dollars — albeit by the way of knockout — and just propped him up ahead of his next fight seems apropos.

Maybe McGregor was mad that Mayweather wouldn’t pick him in the fight.

“I don’t really have a prediction because I’ve never seen the guy fight that’s facing Conor McGregor — from what I know he’s a hell of a guy that’s on the ground — hell of a grappler — and he can wrestle,” Mayweather said.

Or maybe McGregor was just being McGregor.

UPDATE:

Mayweather dropped the nice-guy routine after McGregor’s F-bomb.
