The retired duo will face off in a Spring showdown, TMZ reports.

Tyson, who confirmed the news on Instagram on Thursday night, will enter the ring again aged 59.

The heavyweight king sparked health concerns during a fight against Jake Paul last year.

He struggled in the clash against his younger foe.

And unbeaten 48-year-old is eleven years his new rival’s age.

The 50-0 legend has also been able to keep himself in top shape in retirement.

Tyson’s bout against Mayweather is being organized by CSI Sports/Fight Sports.

An exact date and location is not yet known.

“This fight is something neither the world nor I ever thought would or could happen,” Iron Mike said.

“However, boxing has entered a new era of the unpredictable, and this fight is as unpredictable as it gets.

“I still can’t believe Floyd wants to really do this.

“It’s going to be detrimental to his health, but he wants to do it, so it’s signed and it’s happening!”

The exhibition fight will not go towards their professional records.

“I’ve been doing this for 30 years and there hasn’t been a single fighter that can tarnish my legacy,” Mayweather said.

“You already know that if I am going to do something, it’s going to be big and it’s going to be legendary.

“I’m the best in the business of boxing.

“This exhibition will give the fans what they want.”

Mayweather has been named the greatest fighter this century.

He last fought professionally in August 2017 when he took on UFC king Conor McGregor.

‘Money’ also fought Logan Paul in an exhibition bout years later.

Tyson’s last fight against his brother Jake drew 108 million viewers.
