UFC Fight Night 84 video: Scott Askham scores picture-perfect knockout over Chris Dempsey

Scott Askham brought the O2 Arena to its feet Saturday evening at UFC Fight Night 84, scoring a brutal head-kick knockout over Chris Dempsey in preliminary action.

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:
