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 – Libero - Listen
In volleyball, a libero is a defensive player who plays in the back row. It’s a fairly new position, as it was introduced in 1998 – and the libero plays by some unique rules:
► The libero wears a different color jersey from the rest of the team – so they are easily identifiable. Only one libero can be designated for each set of a match.
► The libero can serve, but can't perform an overhead set in front of the attack line, or complete an attack if the ball is above the net.
► The libero is never allowed to rotate to the front line.
► The libero is the first line of defense, often passing to the setter and covering open spaces.
► The libero can be replaced without restriction – but in the event of an injury, can only be replaced by the player the libero originally replaced.

Be the Referee: Field Hockey Substitutions

Below is this week's segment – Field Hockey Substitutions - Listen
We’re on the pitch today for a field hockey “You Make the Call.”
The white team is awarded a penalty corner. During the penalty corner, a red team substitute enters the field but does not participate in or affect play.
Should the official stop play immediately or allow play to continue?
If you said allow play to continue, you are correct. Since the illegal substitute has not participated in or affected play, stopping play immediately would give the defending team an unfair advantage by interrupting the attacking team's scoring opportunity.
Under NFHS Rule 4-4-3, substitutions are not permitted during a penalty corner, except to replace an ill, injured, suspended or disqualified goalkeeper. Officials must recognize the violation and know when to hold the whistle to allow for advantage.
