Reminder on some protocols

WHISTLES - it is not MANDATORY to have an Electronic whistle. You can use a normal whistle under your mask.

LINESPERSON – the home school does not provide Linespersons; each school has their own Linesperson - they will stay on their own side with their team. NO SWITCHING SIDES. (If one schools only has 6-7 players than if the other school is willing to provide a linesperson it’s okay.)

LIBERO’S - 2 Libero’s are used by BOY’S only.

5th SET – (Deciding game) GIRLS’ play to 25 point. BOYS’ play to 15 points There will be no switching sides in the deciding game. Regular score sheet is used for game 5.

GAME BALLS – should be 2-4 Game balls for each set. If school can not provide 4 than you can go with 2. (All the balls have to be the same.)

STANDING - in front of the benches is allowed

SUBSTITUTIONS – enter the court between the Attack line and the End line.

COIN TOSS – can be done by the R1 stand or any where that you have social distancing from the other players. (R1 and one Rep from each school)

UNIFORMS – point of emphasis – if there is something wrong or questionable about the team’s uniform – email Andy ( or Jim Best if you took a picture. Ex: Team uniform #, Libero’s non-contrasting color. Number # 00 is NOT legal.

R1 or R2 – the protocol is to talk to your partner to decide who will work as R1 or R2. Do not automatically assume you are R2.
