Alright, let's put this to bed. I think anyone trying to claim Carter deliberately kicked Petti Pagadizaval in the head -- or even kicked him at all -- is drawing a loooooong bow (at best it's a glancing stumble).
Carter's moving in to try to tackle when Petti Pagadizaval dives over at an angle that cuts in front of the trajectory Carter's already running (unavoidable). Carter's leaning over and trying to
grab at the lock, not trying to kick him.
The replay gives three different angles of the try, one from above (
vid here) and one from the touchline (
vid here). But it's the third angle, the one from behind the try line, to pay attention to (
vid here):
Carter's hand is in front of his leg, and it's his hand that makes contact with the lock's neck. If you break that down, it's not even clear if its leg makes contact with his own arm, or if he falls over the Argentinian before he has a chance to put a boot to his noggin.
If you think this is still a kick to the dome, feel free to put a friend on the ground, run at them while bent over, stick your forearm down in front of your shin, and then kick your forearm into your friend's head. Then tell us how that goes.
