Below is this week's segment – Behavior Warning - Listen
A new rule in basketball this year allows for an official to warn a coach or team for misconduct. This is an administrative procedure, which is reported to the scorer’s table, but has no immediate penalty.
Stopping play and letting the coach or bench know that a formal warning has been issued sends a clear message to everyone in the gym, and it should also impact behavior in a positive way without having to award a technical foul.
If the official, however, deems the misconduct to be major, a technical foul can be issued. A warning is not required before calling any technical foul.

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.
