The Dublin light middleweight takes on five-weight champion Floyd Mayweather [49(26)-0] on Showtime pay-per-view where he will look to pull off what many say would be the biggest upset in boxing history.
McGregor is currently in Dublin, where he is sparring with pros Louis Adolphe and Dashon Johnson alongside Tyrone amateur welterweight Tiernan Bradley, and he will relocate to Las Vegas soon where he will link up with former two-weight world champion Paulie Malignaggi.
The Crumlin fighter, a two-weight UFC champion, last night released a promotional video showing footage of him hitting the bags in training – while the audio of his now infamous rant at boxing media at Mick Conlan’s pro debut plays over the clip.
