Casey O’Neill Hits Pop Up Armbar At UFC 331

Casey O’Neill pulled off one of the most unique submissions in history at UFC 331.

Facing Eduarda Moura in a women’s flyweight bout, O’Neill found herself on her back after surviving a d’arce choke that looked rather tight in the first round.

O’Neill used her feet to push the hips of Moura, elevating her into the air. She then immediately transitioned into an armbar, snatching Moura’s arm on the way down. Moura quickly submitted.
