2-4-1b: A referee shall stop play when any player gains an illegal advantage by contacting any team member while attempting to play the ball. Team members consist of all school representatives located in the team bench area, including but not limited to coaches, teammates, managers, certified athletic trainers and players. (6-1)
5-5-3b(10): The second referee, as outlined in the Officials Manual, has the responsibility to ensure that the head coach remains in the replacement zone no closer than 6 feet to the sideline, when standing during play. This specific responsibility of the second referee is now outlined in the rules book in an effort to align the responsibilities of each official in both NFHS volleyball publications.
5-5-3b(13), 5-5-3b(20), 5-8-3a NOTE: As established in 2017, the defining end of a time-out or interval between sets shall be the audio signal (horn) administered by the official timer and the warning (double-whistle) of the impending end of the time-out administered by the second referee. It is now clarified in the timers responsibilities that when multiple courts are in use, the second referee may end a time-out or interval between sets with a long whistle in place of the timer sounding an audio signal (horn).
9-8-2 EXCEPTION, 11-4-1b: The exception establishes that when a replay is signaled due to an injury or illness and the injured/ill player cannot continue play, the head coach may request a substitute or complete a legal libero replacement for the injured/ill player or take a team time-out(s) if the team has remaining time-outs. This change also adds the option to complete a legal libero replacement for any injured/ill player.
10-2 PENALTIES 2: In an effort to eliminate further delay of a set, once a team is charged with an unnecessary delay, the coach may not request any further substitutions until the next completed rally. Officials shall deny a substitution request once an unnecessary delay has been charged to that team until a subsequent rally has been completed.
11-5-3: Continuing the focus on risk minimization, the committee has established parameters for warming up between sets. Teams may warm up in their playing area, but may not hit volleyballs over the net into the opponents playing area.
NFHS OFFICIALS SIGNALS #21: The unnecessary delay signal has been simplified by the committee in an effort to eliminate awkward mechanics with the use of the card. To signal unnecessary delay an official will raise the hand on the side of the offending team beside the head, palm facing in, holding the appropriate card on the wrist of the raised hand.
