Floyd Mayweather may have dismissed talk of an MMA version of his superfight with Conor McGregor, but that hasn't stopped him increasing speculation of a cross-code switch.

Hours after posting a picture of their battle last August, the unbeaten American boxer posted a video on social media which showed him stepping inside the octagon.

And if it was a ploy to generate a response from the UFC lightweight champion, it had the desired result, with McGregor responding:

McGregor has repeatedly challenged Mayweather to face him in the octagon, but Mayweather has always brushed it off.

Mayweather defeated McGregor by TKO in their Las Vegas megafight, at the T-Mobile Arena.
