I have to agree on pinching in and keep pinching in until you find the ball and determine if it got in or not. Sometimes it maybe after the player is on the ground. The R and U can help a little, i.e. R saw a knee on the ground and then the player wiggle more forward. Either way the wings need to pinch as quick as possible, even start pinched some if they can.

As far as the original question, The idea is to get the wing official that made that call to get it right with a series of questions along the lines of the rules being played. You have PI, holding, or illegal use of hands in this situation. My questions led him to realize the offense was put at no disadvantage on the play. If he said that the defender knocked the receiver off his route with the bump then it would have an S42 and 10 yards. If he comes up and is insistant that B fouled A, he would need to tell me what he did. If he can't then I wave it off, no as an overrule, but as I don't have anything to call/signal.

I had a WH overrule me on one. I flagged a player for a late hit. The flag went against a team getting the butts handed to them. Told the WH what I had and he said "Well since I didn't see it then i am waving it off because the losing sideline is getting out of control and this will probably push them over the edge." I told him after the game I will never work another game with him ever.
