Naoya Inoue vs. Marlon Tapales undercard: Complete list of fights before main event in 2023 boxing match

History could be made in Japan when Naoya Inoue and Marlon Tapales clash to determine the undisputed bantamweight champion on December 26. The fight airs on ESPN+ in the U.S.

Inoue (25-0) is a four-division champion, consistently fighting for gold since 2014. The former light flyweight, super flyweight, and bantamweight champion beat Paul Butler in 2022 to become undisputed at the bantamweight level. Always up to challenge himself, Inoue ran through Stephen Fulton in July to become the WBC and WBO super bantamweight champion. Now, “The Monster” aims to become an undisputed champion in another weight class and would become only the second male fighter to do so. 

“I’m more motivated than before, and that has exceeded my expectations,” Inoue said via Kyodo News. “I’ve been training on the premise that I’ll be facing a skilled all-round boxer. I’ve gotten myself into better condition than I was for the Fulton bout. Tapales is looking to pull off an upset, so I’ll be careful.”

Tapales (37-3) is a two-division champion, winning WBO bantamweight gold in 2016. On a four-fight win streak, the “Nightmare” beat Murodjon Akhmadaliev in April for the IBF and WBA super bantamweight belts. The 31-year-old has 19 wins via knockout and will look to add the favorite in Inoue to his collection of wins via the power punch.
