George Roop landed 
a vicious left kick to Chan Sung Jung‘s head in the second round of their fight at WEC 51, knocking Jung unconscious and ending the fight suddenly and dramatically.
Jung, better known as The Korean Zombie, became a fan favorite for his brawl with Leonard Garcia at WEC 48. But that fight was full of sloppy technique and lacking in any defense, and Roop showed against Jung how easy it is for a fighter to exploit those problems.
