Article 14: Twisting, Pulling, or Turning the Facemask. No player shall grasp and control, twist, turn, push, or pull the
facemask of an opponent in any direction.
Note: If a player grasps an opponent’s facemask, he must immediately release it. If he does not immediately release it and
controls his opponent, it is a foul.

The Defender also never had his hand inside the collar for a Horse Collar or grabbed the back of the player pulling his forward motion back resulting in buckling the runners knees. His arm was clearly draped around the runners neck and his weight bent over the runner bringing him to the ground.

Let me tell you a little secret. In football if you tackle a player around his head there will be a flag thrown. You cannot grab any part of the helmet, mask, back or side. With the state of head injuries the head is a no go. Its just one of those things that they will call EVERY TIME. You also have the advantage of a slow mo replay and at regular speed and having one shot to do so 99% of all referees are throwing that flag.
