Boxing legend Floyd Mayweather has sparked rumours that he's set to stay unretired and fight again.
The 50-0 undefeated champion came out of retirement to fight UFC star Conor McGregor last month, a victory that was thought to well and truly be his last bout.
But Mayweather has ignited a fan frenzy by posting a video of himself training in the gym.
As you can see in the video above, the 40-year-old looks to be in serious preparation for another fight, after reportedly netting around $100 million for the McGregor showpiece.

Perhaps the man they call 'Money' just can't resist the lure of another payday?
The fact that Mayweather posted the videos to his own Twitter account has many fans claiming he's sending a message that he won't be heading back into retirement any time soon.

I reckon the only way Mayweather would earn respect from EVERYONE as the GOAT is if he come out of retirement to fight Triple GGG and won— Nav (@li_amj) October 19, 2017
