Floyd Mayweather is odds-on at -400 in the boxing and MMA betting to beat Conor McGregor on August 26 at the T-Mobile Arena in Las Vegas in a fight which sees two of the biggest names in the sporting world clash. Talks had been going on for a number of years between the two parties, however, a deal was finally reached back in June for the two men to meet in a 12-round boxing match in a fight which is set to be broadcast on pay-per-view around the world. Mayweather goes into the clash with a professional record of 49-0. His most recent win was against Andre Berto after which he retired from the sport to concentrate on other projects. Perhaps Mayweather’s most prolific venture has been his promotions company, where he works with a number of fighters including world champion Gervonta Davis, who is set to defend his IBF super-featherweight title on the undercard in Vegas. Two-time UFC world champion McGregor is +300 in the betting with the bookmakers to pull off an upset and become the first man to beat Mayweather in a professional boxing contest. The Irishman is expected to be heavier on the night and will be hoping his MMA skills will help him catch ‘Money’ in the ring. McGregor has not been involved in a fight since he defeated Eddie Alvarez with a KO punch in the second round of their clash last November. The Irishman has only lost twice before in the Octagon, with his most recent loss coming against Nate Diaz in March 2016. He did, though, avenge that defeat to Diaz in a rematch five months later. The undercard to Mayweather-McGregor is also set to include the WBA title fight between Nathan Cleverly and Badou Jack, while Andrew Tabiti is set for a stern test against experienced cruiserweight Steve Cunningham earlier in the evening.
