We had intentional grounding called twice in a 7th grade game and the officials gave them a five yard penalty from the previous spot with a loss of down. I thought this was a spot foul with loss of down. The spot was significantly beyond five yards. When I asked the officials they said that in the INFC spot fouls were marked from the line of scrimmage rather than the spot of the foul (holding and block in the back). They weren’t 100% sure how to treat grounding but went with five yards from line of scrimmage. Just curious what the INFC rule is.
