OFFICIAL: Conor McGregor and Floyd Mayweather will fight in August

August 26.

Las Vegas. Conor McGregor v Floyd Mayweather. The best of MMA against the best of boxing. At boxing. It might seem a little unfair but Conor McGregor isn't bothered.

For his tweet to confirm the fight, Conor McGregor used an image of Floyd senior - the height of disrespect to Jr who has won all 49 of his professional boxing fights to date. https://twitter.com/TheNotoriousMMA/status/875101558584856578 Mayweather went with the more professional approach, releasing a video to confirm the appointment. https://twitter.com/FloydMayweather/status/875104754334023680   The event will solely be a boxing card with Mayweather Promotions running the show. Conor McGregor is a boxer now.
