UFC 299 Sean O'Malley vs Marlon Chito Vera live results and ...

Almost four years ago, Sean O'Malley suffered the only loss of his career and it came against Marlon ''Chito'' Vera. Tonight, he'll try to prove that loss was a fluke.

O'Malley (17-1) will defend his UFC bantamweight championship for the first time when he meets Vera (23-8-1) in the main event of UFC 299 at Kaseya Center in Miami. O'Malley lost via TKO in 2020 after a nerve in his right foot went numb from a Vera leg kick. O'Malley has given Vera credit for landing the kick, but has always maintained that it wasn't a "true" loss because of the rarity of the nerve issue.

Both bantamweights have enjoyed a lot of success in the time since. O'Malley captured the 135-pound championship last August by knocking out longtime champ Aljamain Sterling. Vera is 5-2, with wins over multiple former champions in Frankie Edgar and Dominick Cruz.

Also on the card, veteran lightweight Dustin Poirier will make his 30th appearance in the Octagon, opposing French up-and-comer Benoît Saint Denis; Kevin Holland faces Michael "Venom" Page in Page's UFC debut; Gilbert Burns aims to stop the rise of Jack Della Maddalena; and Song Yadong looks to top former bantamweight champ Petr Yan.
