MMA fighter Connor Mcgregor (R) removes his glasses to glare at boxer Floyd Mayweather Jr. as they face-off during a media press conference August 23, 2017 at the MGM Grand in Las Vegas, Nevada.
Mayweather, the 40-year-old undefeated former welterweight boxing champion, has been lured out of retirement to face McGregor, a star of mixed martial arts' Ultimate Fighting Championship. The two men meet in a 12-round contest under boxing rules on August 26th that is tipped to become the richest fight in history.
