After getting taken down by the Pennsylvania native early, Askham scrambled to his feet, and the knockout followed soon after. A left hand put Dempsey on wobbly legs, and a perfectly timed shin to the face followed.
The UFC's official Twitter account captured the action:
With the victory, Askham improves to 14-2 (2-2 UFC) as a professional. Dempsey falls to 11-4 (1-3 UFC).
