It has also been confirmed by the Nevada State Athletic Commission that the fighters will wear 8oz gloves for their non-title, light-middleweight match-up. Byrd, incidentally, oversaw George Groves' 2015 defeat by Badou Jack as well as further high-profile fights in Andre Ward's first win against Sergey Kovalev and Saul Alvarez's victory over Miguel Cotto.
