Sean O'Malley returns to the Octagon to defend his bantamweight championship against Merab Dvalishvili.

O'Malley has won six of his last seven fights, with the other being ruled a no-contest after an accidental eye poke. Dvalishvili earned a title match after winning 10 straight fights, nine of those wins coming by unanimous decision.

Valentina Shevchenko will fight women’s flyweight champion Alexa Grasso in the co-main event. It will be the third fight between the two fighters.

Shevchenko lost the title to Grasso in the first fight by submission at UFC 285 in March 2023. Grasso and Shevchenko’s second fight ended in a split-decision draw.

Sean O'Malley vs. Merab Dvalishvili: Tale of the tape

UFC 306 Predictions

Action Sports Network: Merab Dvalishvili over Sean O'Malley

Sean Zerillo writes "I projected the fight to end inside the distance 54% of the time (-117 implied odds) compared to consensus odds nearer to -115. O'Malley is a threat to close the show anytime during the fight. Still, I feel Merab's finishing chances – either via injury (with O'Malley's historical ankle/foot issue) or cardio-based stoppage in the championship rounds are being undersold."

MMAmania: Merab Dvalishvili defeats Sean O’Malley

Jesse Holland writes: "The challenger has the conditioning to spam takedowns for all five rounds and I’m not sure O’Malley — taken down six times by Petr Yan at UFC 280 — has the defense to stop him. I just don’t feel comfortable picking the champion on the slim chance he can land the kill shot before getting double-legged into oblivion."

MMAjunkie: Merab Dvalishvili beats Sean O'Malley by decision

Dan Tom writes "I have a feeling that my initial lean toward an O’Malley knockout is the correct call, but I also believe that Davlishvili could be one of the toughest stylistic matchups for the champ outside of Umar Nurmagomedov. For that reason, I’ll semi-reluctantly side with the arguably more durable fighter in Davlishvili to survive the early storm and pull away down the stretch (possibly earning a late finish if O’Malley’s body fails to hold together)."
