UFC welterweight Erick Silva can be seen in this clip from several months ago landing an absolutely brutal back kick to the body of his opponent, who quickly drops to the mat.

This kick will definitely make you cringe.

Was it fair game, or should Silva had taken it easier on his sparring partner?
