You wouldn't look to have AWJ suspended for putting Horwill in a dangerous position where he could have seriously twisted, sprained or maybe broken his ankle via the facial contact to Horwill's boot?
I'm sure there's a Law somewhere that would back it up..
10.4 Dangerous play and misconduct
(a)
Punching or striking. A player must not strike an opponent with the fist or arm, including the elbow, shoulder, head or knee(s).
AWJ's vicious headbutt of Horwill's boot was extremely dangerous.
