McGregor, a 28-year-old southpaw, is the first UFC fighter to simultaneously hold titles in two different divisions and one of the best MMA fighters in the world. He will be making his professional boxing debut against Mayweather, one of the greatest boxers in history.

In Mayweather’s last fight, he defeated Andre Berto in a unanimous decision to tie Rocky Marciano’s undefeated record of 49-0. Mayweather was credited with winning every single round on one of the judges’ scorecards.

McGregor last fought on Nov. 12, 2016, when he defeated Eddie Alvarez three-minutes and four-seconds into the second round and took home the UFC lightweight title.
