On 4th and long today at a junior high game playing by NFHS rules, I had B sacking the the quarterback and as he did, he grabbed the back opening of the helmet and quickly released it.

15 yards in Canada. No option for just 5.

I thought I would check afterward just to make sure I was right and I can't find it anywhere in the rule book where it states anything like that.

Anyone have any insight?

Thanks for the help.

Rookie,

I think you need to be a bit more sure of yourself. You can't find it anywhere in the rule book or case book? Then it is not there. The only way it could be 15 automatically if on the QB is by philosophy. Such a beast would have to be a rule, IMO.
