In all contact sports, the biggest issue of the day continues to be concussions. Game officials play a vital role in keeping athletes safe on the field, court, ice and mat.
While officials are never placed in the position to diagnose a possible concussion, the officials can often see when a player first becomes injured. When that possible injury is noticed by an official, all game rules require the contest be stopped and the student is evaluated by the school’s health care team.
It then becomes the call of the school to determine if the player has suffered a possible concussion. If yes, the player is out for at least the rest of that day. If no, the player can return to the contest.

Be the Referee: Volleyball Libero Uniforms

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.
