In just the first round of her flyweight debut the grappling ace stunned her opponent with a right straight to the chin. Once it got to the mat Dern needed only seconds to finish with a rear naked choke, officially at 2:55 of round one.
The fight marks her second submission victory in four fights and could set her up for a shot at the promotions recently vacated flyweight title. Check out the finish below:
