ESPN's No. 3 pound-for-pound fighter, Merab Dvalishvili (21-4), will defend his bantamweight title for the fourth time this year at UFC 323 in Las Vegas on Saturday (10 p.m. ET on ESPN PPV; prelims beginning at 6 p.m. on ESPN+). The nine-year UFC veteran from the country of Georgia is taking on former champion Petr Yan (19-5) in a rematch of their 2023 fight that Dvalishvili won by unanimous decision. If Dvalishvili gets his hand raised for the 15th consecutive time on Saturday, he'll become the first UFC fighter to win four title fights in a calendar year.
