In the final night of a blockbuster three-day boxing marathon, one of the sport’s top talents, Naoya Inoue, seeks to defend his undisputed super bantamweight titles against Ramon Cardenas.
Inoue (29-0, 26 KOs) is Uncrowned’s No. 3 pound-for-pound fighter in the world. A superstar in his native Japan, “The Monster” is a four-division world champion and one of only three male boxers of the four-belt era to become undisputed champion in two different weight classes, having done so at bantamweight in addition to his current super bantamweight reign.
