Hatton got a point deducted for good reason

First of all let me just ask you all to go back and watch what happened. Floyd and Hatton are in tight. Floyd ducks down from the right hand and Hatton falls back behind Floyd a little. Hatton then moves him with his body and left hand on the back of Floyd's head into and thru the ropes, then tries to throw a right hand at the back of the head as Floyd falls thru. I'm sorry, but if this isn't considered a completely obvious and dirty foul then nothing is. Maybe it was difficult to see in real time, but its very obvious when you rewatch the fight.
