On this photo, Mayweather replied: “If I’m not mistaken, didn’t you tell Mike Tyson you could beat me if we fought a second time? Now you”re quitting! I thought you wanted to beat the best? Well, if you decide to come back, I will be waiting to punish you again.”

This is not the first time McGregor has decided to quit fighting as he had earlier tweeted twice about retirement, both times when he was involved in arguments with the UFC. His last fight came in January against Donald ”Cowboy” Cerrone which he won and he has since expressed interest to face a number of opponents.

He was tied this summer to face current top lightweight contender Justin Gaethje. A trilogy fight with Nate Diaz was also something he expressed interest in repeatedly and had also tweeted on May 28 that he had accepted a proposal for a fight against MMA legend Anderson Silva.
