OPI on 4th Down
 

4th down and there is an offensive pass interference penalty. Do you march off the 15 yards then give the ball to the defense?

OPI has loss of down?

It's either first and 10 for B at the previous spot, or 4th and what it was +15 yards for OPI for team A.

Or am I missing something here?

Absolutely.


Yes, OPI carries LOD.

15 yard peanlty, the loss of down results in the down not being replayed. 1st down for B.

wait... I'm talking NCAA/IFAF, sorry

NCAA took out the loss of down from this decades ago.

All LOD means is the loss of the opportunity to repeat the same down after the penalty. So if it is 4th down and the line to gain is not achieved, then you give the ball to the defense/receiving team.

This is an excellent way of thinking about what LOD is.

When I train officials with a similar phrase, it helps make it clearer what the next down is for those certain fouls that carry the "LOD".

Canadian Ruling
 

CANADIAN RULING:

OPI is 15 yards (unrestricted) and repeat the down. 15 yards and a potential turnover is too much, imho.

I think most here speak NFHS unless NCAA is stated.

What is IFAF?

Peace

I have better things to do. What the hell is IFAF?

Peace

International Federation of American Football

And that the hell is that?
