LAS VEGAS – Sean O’Malley and Merab Dvalishvili took care of their most important pre-fight business on Friday as they qualified for the main event of UFC 306.

Bantamweight champion O’Malley (18-1 MMA, 10-1 UFC) will look to make his second title defense when he takes on Dvalishvili (17-4 MMA, 10-2 UFC) in the headliner of Noche UFC at Sphere (ESPN+ pay-per-view, ESPNews, ESPN+).

It was a professional scene at the official weigh-ins at the UFC Apex, with O’Malley hitting the scales at 135 pounds. He was also the first to arrive. Challenger Dvalishvili stepped onto the scale about 15 minutes into the session and weighed in at a pound under 134.
