Floyd Mayweather has confirmed he will fight Conor McGregor on August 26 in Las Vegas
McGregor took to his Twitter page to tell the world the fight has finally received the go ahead
Whether the boxing purists take to the notion or not, this will be the biggest grossing event in the history of combat sports since Mayweather and Manny Pacquiao finally got it together to the tune of more than half a billion dollars between them.
Although this will be The Notorious Irishman's first orthodox boxing match and Mayweather will go into this cross between a fist fight and a circus spectacle, the Nevada State Athletic Commission have assured their Mr Money that all the relevant licenses and approvals will be forthcoming.
Not surprising that, since the casino drop from high rollers and sports punters will guarantee a bonanza for everyone,.
Mayweather is on a minimum certainty of $100million, plus the upside on high sales by Showtime, the major US cable network.
For weeks McGregor had been fuelling the fire by posting pictures of himself in boxing training
McGregor's share of the bounty is thought to be in the region of $80m but a percentage of that will go to the UFC, his paymasters in his customary field of action mixed martial arts.
Mayweather, as astute a politician as he is a boxing genius, has timed the event to somewhat upstage his old adversary Oscar de la Hoya's staging of Mexican idol Canelo Alvarez against middleweight knockout supremo Gennady Golovkin.
De la Hoya stole the Mexico independence weekend date of September 16, when Mayweather has always preferred one of his two matches a year so as to draw large crowds across the border.
The Vegas casinos have their own take on how competitive the fight is likely to be, or otherwise. They quote Mayweather as an 1-8 favourite.
McGregor, at an outsider's 5-1, insists that he has always been a knockout rather than a kick over and grapple UFC man and has been in strict boxing training now for more than two months.
