O'Malley vs. Dvalishvili – Odds, Lines, Special Bets and Tips

The UFC is set for tomorrow's UFC 306 fight card at the Sphere in Las Vegas, which will stream on ESPN+ pay-per-view. UFC 306 features two title fights at the top of the card. In the main event, UFC bantamweight champion Sean O'Malley will face No. 1 seed UFC 135-pounder Merab Dvalishvili. In the co-main event, current women's flyweight champion Alexa Grasso will face former champion Valentina Shevchenko in a trilogy contest.

O'Malley won the UFC bantamweight title in August 2023 via a TKO victory over Dvalishvili's teammate Aljamain Sterling. He defended his title for the first time in March, scoring a one-sided decision victory over Marlon “Chito” Vera. Dvalishvili is coming off a decision victory over former two-division UFC champion Henry Cejudo in February.

Grasso ended Shevchenko's long run as women's 125-pound champion in March 2023 when she handed Shevchenko the first submission loss of her career. The two faced each other in a rematch in September 2023. That fight ended in a draw.

The UFC 306 main card, also called Noche UFC, will stream on ESPN+ pay-per-view at 10 p.m. ET. ESPNews prelims begin at 8 p.m. ET, following early prelims on ESPN+, which begin at 7:30 p.m. ET.

Below we look at the betting odds, line movements, possible special bets, fight tips, predictions and more for tomorrow's UFC 306 fight card.
