Floyd Mayweather has fired another shot at Conor McGregor, offering $10,000 (£7,984) to the person who provides the best caption to images of the UFC champion tapping out.
The two have been engaged in a feud that has intensified over the past few months, with speculation growing that the two men could have a multi-million-dollar showdown inside a boxing ring.
Mayweather retired from boxing last year, with an unbeaten record of 49-0, and posted a video mash-up on Instagram of McGregor's UFC 196 defeat to Nate Diaz in March 2016.
A message at the end of the film reads: "49-0 vs Conor The Notorious Quitter."
McGregor, the reigning UFC lightweight champion, was recently granted a licence to box in the state of California, making the possibility of a fight more likely.

But the move was dismissed by the Mayweather camp who described it as a "con job" from the Irish fighter to "keep his name alive".
The winner of the contest will be announced on Monday, 19 December.
