Free Kick after fair Catch?
 

Read one post on another website where the following scenario played out.

R1 calls for a fair catch. On the next play B25 commited DPI and the penalty was then accepted. A then elected to have a free kick following a fair catch.

The logic that was illustrated was that since B had commited a penalty that was accepted it was like that play had never happened and therefore could take the free kick after a fair catch.

Didn't see any discussion on this scenario just the first statement. Whats the ruling?

NFHS 4.3.7 is this exact situation.
