Mayweather takes on Argentina's Marcos Maidana in what is more than a re-match: it is the first of his three remaining fights, aiming extend his unbeaten run to 47 wins.

If the American come out on top in his three remaining bouts he will equal Rocky Marciano's 49-fight unbeaten record.

But he insists he will not be tempted to have one more fight to break the record as he changes his focus to growing his promotional company.

It means British duo Amir Khan and Kell Brook, who both want to meet Mayweather, are running out of time to grab their chance.

He said: "I have only got two more fights after this. After those fights I just want to build the Mayweather Promotions brand.

"As of right now my focus is on Maidana. I can't focus on the two fights after this. I can't say who the next two opponents will be, but they will be exciting fights.

"My next fight is in May and then September. A year from now will be my last fight."

Mayweather will defend his WBA (Super), WBC and WBC Light Middleweight titles against Maidana who he beat on points in May.

'Money' Mayweather - who has career earnings of over £300m - is defying age to stay at the top of the sport for so long.
