If you actually watch the footage, it appears that Chuck was flash KO'ed first (the initial fall), which is why he tries to move his legs. He still has control of some of his faculties...Then Rampage KO's him on the ground, followed quickly by a strike that revives him, but Big John already stopped the fight at that point. Rampage did a beautiful counter to the body shot. Well done Rampage and Good Luck with Dan Henderson.
