Substitutes: NHSA Part 1, Q#65

[ocreferee]

T or F - It is permissable to withdraw a player before the clock properly starts following his or her substitution into the game.

I know it is true for all codes but can only find the NCAA reference 3-4-12 "A player who legally enters the game during a dead ball may leave the game during that same dead-ball period without penalty."
