Conor McGregor confident he will knock out Floyd Mayweather - UFC chief Dana White
UFC superstar McGregor and Mayweather will finally lock horns in a blockbuster boxing event on August 26 at the T-Mobile Arena in Las Vegas.
The bout will be contested over 12 rounds at 154 pounds with both fighters wearing 10 ounce gloves, and it could smash all box office records for a fight.
Mayweather holds a formidable unbeaten record of 49 wins with no defeats in the squared circle, but the Irishman is hoping to upset all the odds.
White told TMZ: "We've been working on this for a long time; the negotiations were a lot better and smoother than I thought they would be.
