Here are key parts of the Rule 9-1-4 relevant for this instance. It is beyond me how they can possibly overturn this decision based on the rules as they are written.
No player shall target or make force able contact to the head
or neck area of a defenseless opponent with the helmet,
forearm, hand, fist, elbow or shoulder. This foul requires that there be at least one indicator of targeting (See Note 1 below).
When in question, it is a foul (Rules 2-27-14 and 9-6). (A.R. 9-1-4-I-VI)
Note 1: "Targeting” means that a player takes aim at an opponent for purposes of
attacking with forcible contact that goes beyond making a legal tackle, a legal block or playing the ball. Some indicators of targeting include but are not limited to:
- Launch. A player leaving their feet to attack an opponent by an upward and forward thrust of the body to make forcible contact in the head or neck area.
- A crouch followed by an upward and forward thrust to attack with forcible contact at the head or neck area, even though one or both feet are still on the ground.
- Leading with helmet, shoulder, forearm, fist, hand or elbow to attack with forcible contact at the head or neck area.
- Lowering the head before attacking by initiating forcible contact with the crown of the helmet.
Note 2: Defenseless player (Rule 2-27-14).
When in question, a player is defenseless. Examples of defenseless players include but are not limited to:
A player in the act of or just after throwing a pass. This includes an offensive player in a passing posture with focus downfield.
A receiver attempting to catch a forward pass or in position to receive a backward pass, or one
who has completed a catch and has not had the time to protect themselves or has not clearly become a ball carrier.
