What happens when a Libero replaces another Libero in the match?

When a Libero replaces another Libero in a match, it is crucial that the referee be informed immediately. This is because the Libero has specific rules and restrictions that govern their participation in the game. By notifying the referee, it ensures that all procedural requirements are met and that the match can proceed smoothly without any disruptions. Referees keep track of player changes and must be aware of which Libero is currently on the court to enforce the rules accurately. Proper communication with the referee maintains the integrity of the match and keeps the game flowing correctly.
