Floyd Mayweather Jr

McGregor calls out Mayweather

Mayweather stopped McGregor in the 10th round when the UFC superstar made his professional boxing debut in August 2017.

The unbeaten Mayweather retired for the third time after that bout, but announced last November that he would resume his career yet again in 2020 for a "spectacular event".

McGregor will make his UFC comeback against Donald 'Cowboy' Cerrone on Saturday and the 31-year-old Dubliner took the opportunity to call out Mayweather prior to the fight.

McGregor, though, surprised many by going toe to toe with Mayweather until the 10th round.

"He's a lot better than I thought he was," Mayweather said after the bout.

Mayweather is the first boxer to reach 50 fights undefeated. After today’s win, he said this was the final fight of his career.

The only certainty of this fight was that it would be a spectacle not seen before.

White: McGregor will become the biggest star on earth

UFC superstar McGregor will make his boxing debut in Las Vegas after luring Mayweather out of retirement for the blockbuster event.

Given Mayweather's 49-0 record the American has been installed as strong favourite for the fight, but McGregor's odds have continued to come in as the bout draws closer.

And UFC boss White believes McGregor is going to shock the world by knocking out his illustrious opponent, and in turn make him the "greatest combat sports star ever".

"To think Conor can't beat Floyd Mayweather is quite something," White told BBC Sport.

Smaller gloves approved

Nevada boxing regulators on Wednesday (Thursday NZ time) gave the two fighters an exemption to a rule requiring 10-ounce gloves for fights at 154 pounds (69.8kg), approving eight-ounce gloves for the August 26 bout. Representatives of both fighters appeared before the Nevada State Athletic Commission to request the waiver.

Commissioners also approved veteran referee Robert Byrd as the third man in the ring for the fight.

Parker towers over Mayweather

The Kiwi heavyweight has been welcomed into the camp of Floyd Mayweather Jr, who is getting ready for a big fight of his own, against Mixed Martial Arts star Conor McGregor.

Mayweather quit boxing in September 2015, with a 49-0 record, but has come out of retirement to fight McGregor, who has a 21-3 MMA record and is notorious for his trash talk.

Mayweather was not the tallest man, though renowned for his reach across the various fly, light and welterweight classes in which he has fought. He was 173cm tall compared with Joseph Parker who measured in at 193cm.

Mayweather to fight McGregor in August

The pair have been trading verbal blows for months and a deal has been a long time coming despite both men stressing they were keen for the fight to take place.

However, that all changed on Wednesday after the Nevada State Athletic Commission approved a request put in by Mayweather Promotions to host a boxing match in late August.

Soon after, both Mayweather and McGregor took to social media to confirm the fight will take place, a move that will send shockwaves through both boxing and MMA.
