Looking for a rule reference
 

I am looking for a rule reference for a question of the NFHS Part I test. Let me be very clear here, I DO NOT WANT AN ANSWER, I WANT A RULE REFERENCE ONLY.

This is the question:

It is permissible to withdraw a player before the clock starts following his or her substitution into the game.

Thanks for the help.

Casebook 3.3.3 Situation A

Thank you.

True 3-3-4

That Case Book Play came from this prior interpretation, which elaborates a little more on the reason why this is permitted:

2006-07 NFHS Basketball Rules Interpretations

SITUATION 11: A1 is injured during a play in which he/she was fouled. As a result, A1 cannot attempt the awarded free throws. A6 replaces A1 and attempts the free throws, which are successful. Team A then calls a time-out. At the conclusion of the time-out, (a) A1 is ready to play, or (b) A7 replaces A6. RULING: In (a), A1 may not re-enter the game until the next opportunity to substitute after the clock has properly started. Legal substitution in (b); A6 may leave the game at any time. Substitution restrictions only apply to being withdrawn and attempting to re-enter without the clock properly starting. (8-2; 3-3-4)
