The question of who would win a fight between a boxer and a martial artist is as old as both disciplines. Of course, some attempts have been made at staging such a bout over the years, with the obvious problem being which rules it would be held under. The latest such effort came on August 26, 2017, when Boxing champ Floyd Mayweather came out of retirement to square off with Mixed Martial Arts (MMA) star Conor McGregor. Per Nevada Athletic Commission rules, the bout was held with 10 ounce gloves - significantly more than the 4 ounce gloves McGregor used in the octagon - and Mayweather ran his career record to a perfect 50-0 with a 10-round TKO over the "Notorious" Irishman. Two gloves, one red and one black, are signed by both combatants in crisp silver Sharpie. Both have stickers from PSA and Beckett.
