Japanese fighter Ryo Chonan instantly submits Brazilian champion Anderson Silva with a "flying scissor" take down that transitions mid-air into a heel-hook submission.

In a flying scissor, you jump and put one leg in front of his waist and one leg behind his knees, using your legs as a scissor to take him to the ground.

A heel-hook is a very dangerous submission in which you twist his ankle while controlling his body with your legs, creating severe torque on the ankle and knee.

Silva is forced to tap immediately or suffer a very painful and damaging injury.
