Iowa-Wisconsin - IW

[raiderfan]

Using NFHS rules - I thought the IW called for a replay of the down back at the original LOS.
The only IW I ever witnessed were on scrimmage kicks that were muffed and someone blew an IW. Using the ruling applied in the Wisconsin - Iowa game, the ball was in the kickers possession and becomes loose at the kick. If there is a muff by R , then an IW , then recoverd by K or R , the ball should go back to the line where K kicked the ball and replayed .

Do I have this right ? IW's are rare but if I ever need to rule on one I want to get it right.
