1. What do you do to correct the following errors: (a) a fifth down has been run (when can you and when can you not correct this error.) (b) team A has not been given its allotted 4th down (when can you and when can you not correct this error.)

2. List all cases when you MUST replay a down if there was an IW.

3. List all cases when the team in possession of the ball at the time if the IW has the option of replaying the down or not.

I'll take a chance at these.
 

Go easy on me.

1.(a). Correct it prior to the next snap or free kick.
2.(b). Correct it prior to the next snap or free kick.
Once the next snap or free kick takes place, its too late to correct the error. Misapplications regarding rules need to be corrected prior to the start of the next play.

2. If you have an inadvertent whistle during a kick, you must always replay the down.

3. The team in possession of the ball can replay the down or accept the results of the play at the time of the inadvertent whistle.

REPLY: Likewise for an IW during a <u>legal</u> forward pass...or for that matter during a snap in flight.
