Mayweather posted a video on Instagram of him enjoying a game of table tennis with his cousin Roy.
The former five-weight world champion, who won all 50 of his professional contents, is widely considered the most gifted fighter of his generation.
And since announcing his retirement in the wake of victory over Conor McGregor last year, the 40-year-old has been putting his hands to good use elsewhere.
On Saturday, Mayweather posted a video on Instagram of him enjoying a game of table tennis with his cousin Roy.
The twist? 'Money', who recently flaunted the $100million cheque he received for beating McGregor, was 'fooling around' on his '$30,000 crystal glass ping pong table'.
The short video showed Mayweather was no slouch with a bat in hand. But he could soon be putting his talents to better use – in the Octagon.
It was reported this week that he and McGregr are reportedly in talks over a sensational MMA rematch potentially worth $500million (£360m).
