Below is this week's segment – Back Row Illegal Blocker - Listen
We’re on the volleyball court today where Team A’s back-row setter is in the front zone near the net and jumps to try to make the team’s second contact. The ball enters the plane of the net where Team A’s back-row setter and Team B’s front row player simultaneously touch the ball above the top of the net. What’s the call?
Illegal block on Team A’s back-row setter.
A back-row player attempting to play a ball in the space directly above the net is considered an illegal blocker if the ball is attacked or blocked by an opponent into the back-row player while reaching above the height of the net.
Team B would receive a point and would be next to serve.

Be the Referee: Volleyball Libero Uniforms

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.
Below is this week's segment – Volleyball Libero Uniforms - Listen
Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.
At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.
Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.
This ensures quick identification for substitutions, scoring, and libero actions.
