WATCH: Floyd Mayweather trolls Conor McGregor about his lowest moment in the UFC

He's offering $10,000.00 for a caption.

Despite the fact that Conor McGregor has been issued with a boxing licence in California, we all know that any crossover fight against Floyd Mayweather is not going to happen. The CEO of Mayweather Promotions even said that it's not going to happen but this hasn't stopped 'The Money' from taunting 'The Notorious'. As you may know, Mayweather went the entirety of his professional career unbeaten unlike McGregor who submitted to Nate Diaz at UFC 196, and the five-division world champion is taking great pleasure in this. Aside from an upcoming appearance in Game of Thrones, McGregor is taking some time off to size up his next options before returning to the octagon, but we fully expect a reply to this post that Mayweather shared on his Facebook page.
