The mat official has the responsibility to ensure the safety of all participants and to enforce all NFHS rules and Kansas Kids Modifications to the NFHS rules.
At the State Body meeting each club was provided a current edition of the NFHS rule book in their club packet. The answer to your questions may be found by reviewing rule 3-4-1 (pg. 12) and 4-2-1 thru 4-2-6 (pgs. 16 and 17).
As always, I am prepared to answer any question however I do not guarantee you will like my answer.
