Nathan brown tried to defend It by saying that diverfield was protecting himself. He raised his elbow!!! If I was trying to protect myself I would be tucking my arm in to brace myself for the unavoidable collision, not raising my arm to leave my ribs exposed
A fair while ago Ken Hinkley did exactly the same thing to Tony Hall. But in that instance
a) Hall was going to shirt front Hinkley with no thought of going for the ball and hammer him out of the game; and
b) Hinkley's was clearly a reflex action to raise the elbow.
Hinkley still got weeks for it, and that was back when the head was not sacrosant.
