Sean O'Malley's bantamweight championship will be on the line when mixed martial arts' leading promotion arrives at the Sphere for UFC 306 on September 14.

The promotion will stage its sophomore celebration of Mexican Independence Day on September 14. While Las Vegas is once again the host destination, the Octagon will be in a much different environment this time around.

Instead of the T-Mobile Arena for the second straight year, the 2024 edition of Noche UFC is set to go down inside the unique Sphere venue. In the lead-up, UFC CEO Dana White has promised a spectacle like nothing seen before.

And he confirmed this week that O'Malley will be tasked with closing it out in defense of his belt opposite Merab Dvalishvili. White announced the expected news in a video uploaded to the UFC's social media accounts on Friday night.

O'Malley Targets Second Successful Defense At The Expense Of Dvalishvili

When the pair share the Octagon inside the unique surroundings of the Sphere, O'Malley will be looking to make Dvalishvili the second victim of his title reign.

O'Malley (18-1, 1 NC) captured the 135-pound gold in memorable fashion last August, concluding the Boston-held UFC 292 pay-per-view event with a shocking second-round knockout of longtime champ Aljamain Sterling. The result brought "Funk Master's" record-breaking rule to an end and set up the chance for his teammate to avenge the setback.

While he's had to wait for "Sugar" to settle unfinished business with Marlon Vera at UFC 299 in Miami this past March, Dvalishvili (17-4) finally has his first shot at title glory in mixed martial arts booked in.

The Georgian has had to win 10 straight fights and go unbeaten since 2018 to make it happen. He's most recently defeated three former champs, getting the better of José Aldo, Petr Yan, and Henry Cejudo on the scorecards to leave no doubt about his status as the unrivaled number one bantamweight contender.
