2‑12‑5: The intent of the rule change is to avoid gamesmanship and ensure the time for replacement remains within the rules. This rule change makes 2‑12‑5 consistent with 2‑12‑4 “second horn” requirement.
Rationale: The addition of a warning signal at the end of the replacement period admonishes the coach and team to prepare for resumption of the game.

5‑4‑1, 2: When a coach has been removed, this rule clarifies that if no other coach or school personnel are available, then the game is forfeited unless state association rules determine otherwise.
Rationale: Rewritten to clarify the forfeiture process and adds language and a new article to give directions when there is no coach or other school personnel, on the bench.

10‑6‑Penalty: To clarify that officials are not required to issue a warning prior to issuing a technical foul. However, they may issue a warning when the offense is judged not to be major.
Rationale: To clarify the official does not have to give a warning to the coach. The warning is one of the tools used to help improve behavior before a technical foul has to be given.
