NFHS unreported sub

[shipwreck]

I don't have my NFHS softball rulebook in front of me so I will ask this question. If a defensive player enters the game and doesn't report, and it is brought to the umpire's attention. The umpire gives a team warning and the next unreported player is restricted to the bench, correct? Is it in ASA that if the unreported player makes a play, the offensive coach has an option of taking the play or redue the at bat? What happens in NFHS if there has been a team warning for this already and another unreported sub makes a play on defense? If brought to my attention, she is restricted to the bench and then what? Does the play stand? Dave
