Psk
 

4th and 4 Team A punts. During the kick you have a block in the back by R while the ball is in the air and has crossed the NS. K downs the ball and R never touches it. What are K's choices and the rule number?

If the team-R block is more than 2 for NF or 3 for NCAA yards downfield, then team-K has no choices at all as the foul qualifies as a PSK foul and they will most likely enforce it from the spot where the kick ended.

So I guess you can say the choice is to accept or decline team-R's foul.
RRef is in rule 10.

If the block does not fit the PSK definition for it's location (RRef in rule 2), tyen team-K will want to enforce the foul from the previous spot, giving them a 1st down in your case play.

I dont have my books, but why does 3 yards matter, I was under the impression that if you are talking about the neutral zone, even the expanded neutral zone only goes out for 2 yards...

REPLY: NCAA doesn't have an "expanded neutral zone" per se, but instead uses three yards as its surrogate. Same holds for PSK enforcement--foul must occur at least three yards beyond the NZ.

It doesn't, because I was supposed to type 2 yards for NF or 3 yards beyond for NCAA.
