“The Monster” Naoya Inoue faces Ramon Cardenas on Sunday, May 4, live from T-Mobile Arena in Las Vegas. The pair battle it out in the main event, with the undisputed super bantamweight title on the line. The contest rounds out three days of world-class boxing action on Cinco De Mayo weekend.

Japan’s 32-year-old four-division champion Inoue (29-0, 26 KOs) makes the fourth defense of his title in his first fight in the U.S. in four years. 29-year-old Cardenas (26-1, 14 KOs) of San Antonio, TX, challenges for the division’s major title in his first championship showdown.

Unbeaten 31-year-old Espinoza brings his WBO featherweight belt to the ring, making the third defense of his title.
