Check out this vicious cheap shot during a Sydney AFL match between UNSW/ES and Western Suburbs. The players are seen running towards the action when seemingly out of nowhere, #26 threw a mean left hook to the back of his unsuspecting opponent's head, sending him crashing down to the ground in a heap.
If the offending player had tried this sort of carry on in an Obstacle Course MMA bout, he would have earned his team some valuable points. However, since he landed the haymaker on an Aussie Rules field, the only reward he is likely to get is a lengthy ban and a possibly a fine for his absolutely filthy hit.
