Dern, the 33-year-old Brazilian Jiu-Jitsu specialist, controlled the pace of the five-round championship bout through superior grappling and clinch work. Despite a late-fight surge from Robertson, who looked to leverage her record-breaking submission history, the judges awarded the fight to the Missouri native with scores of 49-46, 49-46, and 48-47. Following the match, Dern noted that while she had hoped to secure a submission, her tactical control proved sufficient to retain the title she first captured at UFC 321.

The undercard featured a volatile lightweight showcase as Jalin Turner dispatched Kaue Fernandes in just 39 seconds. Turner caught Fernandes with a precise counter-uppercut during a spinning back fist attempt, triggering a stoppage that earned him a $100,000 Performance of the Night bonus. The win marks a significant milestone in Turner’s comeback following his brief retirement last year.

In the main card opener, Esteban Ribovics secured a second-round TKO against veteran Edson Barboza. Ribovics dominated the exchanges before referee Herb Dean ended the contest at the 1:32 mark of the second round. The loss prompted Barboza, a 40-year-old staple of the lightweight division, to announce his retirement from professional MMA, concluding a 15-year career.
