R signals for a fair catch. K is stopped 5 yards away from R. Just before the ball gets there R realizes its going to be short of him and leaps from his feet initiating contact with stationary K who did not have time to react, and then muffs the ball and K recovers? I understand R must be given a chance to catch be ball but since K was stationary and R made such an adrubt move that didn't allow K to get out of his way would this still be a penalty on K?
