The four title competitors were first on the scale Friday morning at the official UFC 316 weigh-in with Merab Dvalishvili, Sean O'Malley, Julianna Peña and Kayla Harrison all making weight on their first attempt, rendering both bantamweight title fights official.
Dvalishvili and O'Malley are set to meet in a rematch of their UFC 306 contest that saw Dvalishvili become the new men’s 135-pound champion thanks to a five-round unanimous decision, while Peña is looking to defend the women’s 135-pound title for the first time against Harrison.
A one-pound allowance is given for all non-title bouts, but Dvalishvili, O'Malley, Peña and Harrison each had to weigh no heavier than 135 pounds on the dot. Dvalishvili stepped on the scale at 134 pounds while the other three were an even 135.
Harrison is now three for three on her drastic weight cuts down to the bantamweight limit in the UFC. The 34-year-old was a two-time Olympic gold medallist in judo competing at 172 pounds and a PFL champion in the 155-pound division before signing with the UFC early in 2024. She defeated Holly Holm and Ketlen Vieira to earn a title shot; Peña became a two-time UFC champ when she narrowly beat Raquel Pennington in October after returning from a two-year layoff.
