Check your rule book. I had to show this to a coach last year. Also, an ineligible blocker that drives his defensive player more that three yards is now guilty of PASS INTERFERENCE by RULE. You better make a couple of copies of this and keep with your game card to give to the coach when you make this announcement.
Ineligible Receiver Downfield
ARTICLE 10. No originally ineligible receiver shall be or have been more than
three yards beyond the neutral zone until a passer throws a legal forward pass
that crosses the neutral zone. A player is in violation of this rule if any part
of his body is beyond the three-yard limit. (Exception: If the passer is legally
throwing the ball away and the ball lands near or beyond the sideline.) (A.R.
7-3-10-I and -III).
PENALTY—Five yards from the previous spot [S37].
