Hello everyone, I have a question that I CAN NOT find the answers to, and im really hoping someone here can help.

My brother is in 7th grade going into 8th and has just started kicking/punting for the football team. Im trying to help him get better and i have been doing a lot of research. I bought him the 2'' kicking block and plan on buying him the 2'' kickoff tee also. My problem is his coach has him kicking field goals off the ground and from all my research it says he shouldnt be doing that till college. Long story short I can not find any rules about the kicking blocks and tees. I want to approach his coach about him using the block and bigger tee but i would like to have the rules. Does anyone know where i can find the rules on kicking tee and blocks? Any help would be greatly appreciated
