Floyd Mayweather's two-year-old grandson is already shadowboxing, he's so good it's gone viral

The future of Floyd Mayweather's boxing legacy looks to be in safe hands after footage of the 46-year-old's grandson shadowboxing has gone viral.

Mayweather, who retired in 2017 with an undefeated record having won 15 major world championships, now looks to be passing on the mantle to the younger men in his family.

The American has been spotted previously helping to train his son Koraun in the ring, displaying his unparalleled movement in the process.

Koraun, just 20, will hope to use his father's in-depth knowledge and advice to help navigate his own boxing career.

However, the Mayweather name doesn't look to be ending there, with grandson, KJ, already taking a keen interest in the sport.

Footage of KJ, just two-years-old, shadowboxing on the kitchen worktop has been shared by his family on social media and has since gone viral on Twitter.

He was filmed moving his feet, body, and arms in a motion reminiscent of his grandfather, throwing in a couple of jabs and the odd upper-cut for good measure.

Just two weeks ago, it was his grandfather throwing the punches, when he faced off against John Gotti in his latest post-retirement exhibition fight in Florida.

The fight was fuelled with with endless fouls and foul language, referee Kenny Bayless waved things off in the sixth round, before the ring descended into chaos.

Gotti refused to stand down and charged at Mayweather, sparking a mass brawl that spread throughout the FLA Live Arena, with videos emerging of separate fights within the ring, the crowd, and backstage.

Despite being suspended for six months due to his actions by the Florida State Boxing Commission, Gotti has suggested a rematch with Mayweather could be on the cards.

“We’re in talks right now to do something, so we’ll see where it goes,” Gotti said on the latest episode of The MMA Hour.

“From what I understand, after the fight, it was the most Googled thing in the whole world. So Floyd’s a businessman, Floyd wants to capitalize on that, and he wants to make money.

"If they want to do it again, I’m here. And I promise you this time I’m gonna come out guns blazing as soon as that bell rings. We’re going to fight, now.

“My confidence is through the roof on it happening,” Gotti continued. “He wants to do it. We’re in talks right now, and hopefully the date gets locked in pretty soon. [Looking at] October. You are correct: it won’t be in Florida.”
