Dvalishvili, 34, enters on a 12-fight win streak and fresh off arguably the best win of his career against Umar Nurmagomedov, where he was a betting underdog to the unheralded challenger. O'Malley, 30, has not competed since the loss to Dvalishvili.

Merab Dvalishvili and Sean O'Malley will run it back in a bantamweight title rematch, and Julianna Peña will defend her belt against Kayla Harrison at UFC 316 on June 7, the promotion announced.

The main event and co-main event of UFC 316 are official, with two bantamweight title fights topping the bill in New Jersey. In the headline bout, Merab Dvalishvili will defend his 135lb belt against Sean O’Malley – the man he dethroned in September – while Julianna Pena puts the women’s version of the title on the line versus Kayla Harrison.
