After scoring the biggest victory of his professional career, Sean O'Malley conducted his post-fight octagon interview with Joe Rogan. During the chat, 'Suga' shared how making a single mistake against him could prove harmful to his opponents.

O'Malley then went on to call out Marlon Vera for a title fight at the T-Mobile Arena in Las Vegas in December:

"It only takes one mistake against me. I don't even know if that was a mistake, I'm just that f***ing good... It's just the beginning of the 'Suga' era. I'm runnin this s**t till 2035, baby!... I'll whoop 'Chito's a** in December at T-Mobile. Let's f***ing go, baby!"

Vera and O'Malley first fought at UFC 252 where 'Chito' scored a first-round TKO victory.

Now that O'Malley has the title and Vera also won his encounter against Pedro Munhoz, a rematch between the two for the title could possibly be next on the cards.
