The UFC 321 co-main event pitted two jiu-jitsu specialists against each other. However, the fight played out more on the feet than on the ground. In the first round, Dern showed greater poise in the exchanges, landing clean strikes on her opponent. Virna, for her part, also had her moments in the box and sought specific takedowns.
In the second round, Dern continued to be more aggressive in her striking. Even when she was taken down, she proved to be active on the bottom. In the third round, the duel between the Brazilians remained evenly matched and intense. The professionals successfully matched each other in their striking. In the grappling, Virna managed to take Dern down, but she wasn't as effective on top.
In the fourth round, the pace didn't slow down. Dern remained aggressive standing, in the clinch, and on the ground, from below. Experienced, Virna also proved competitive and landed solid strikes on her opponent. In the fifth and final round, the fighters, intent on the vacant belt, exchanged blows with all their might. The fight remained frenetic, with positions being lost. In the final stretch, Dern proved superior and impressed the judges.
