At UFC 306, Merab Dvalishvili captured the bantamweight title by defeating Sean O'Malley via unanimous decision, marking his 11th consecutive win. Dvalishvili showcased relentless grappling and exceptional cardio, dominating the fight with a score of 49-46, 48-47, and 48-47 on the judges' scorecards. O'Malley, who had previously reclaimed his title, struggled to find an answer to Dvalishvili's aggressive pace and grappling skills, resulting in his second career loss. In the co-main event, Valentina Shevchenko reclaimed her women's flyweight title with a commanding win over Alexa Grasso, landing 45 significant strikes to Grasso's 18. The event, titled 'Noche UFC' in celebration of Mexican Independence Day, featured several fighters of Mexican heritage. Notably, the fight was interrupted early due to an altercation between Dvalishvili and O'Malley's coach, prompting referee Herb Dean to intervene.
