The American former professional boxer, who competed undefeated from 1996 to 2015, has announced he will be picking up his gloves again.
Floyd Mayweather has insisted he is officially coming out of retirement to fight Conor McGregor.
Mayweather has gone on record and urged MMA star McGregor to sign terms with his UFC bosses, so the pair can meet in a cross-codes fight this summer.
The five-weight world champion told fans he was tired of hearing excuses from McGregor.
During a public appearance on Friday in Liverpool, Mayweather said “I don't want to hear any more excuses about money McGregor. You're the B-Side, I'm the A-side. If you want to fight, sign the paperwork and let's do it. Let's fight in June."
