Floyd Mayweather Jr has made another sensational u-turn as he claimed last night that his fight with Tenshin Nasukawa is back on.

Mayweather shocked the sporting world when he turned up in Tokyo earlier this month to announce a bout on New Year’s Eve against the unknown Japanese kickboxer.

The fight was going to be against Nasukawa in Tokyo after Mayweather reportedly signed a deal with RIZIN Fighting Federation, a Japanese mixed martial arts company.

Although, once the American return to U.S soil he revealed the whole thing had been a major misunderstanding and he was only supposed to fight three rounds behind closed doors to a select crowd of very wealthy people.

However, Mayweather has now announced the fight is back on in and claimed it is going to be the ‘highest paid exhibition ever.’

“We’re gonna make it happen.

“Rules? It’s gonna be a little boxing exhibition.

“No kicking, I’m moving around with the guy for 9 minutes, and of course it’s gonna be the highest paid exhibition ever.

“It’s a no-brainer. Just because I’m retired from boxing. I still make appearances worldwide and make a ton of money,” the 41-year-old told TMZ.

Mayweather, who has a boxing record of 50-0, is 2/9 to win the bout, while the 20-year-old undefeated kick-boxer is 11/4 outsider.
