Is it permissible for a player designated as a libero to have two numbers on the roster?

In volleyball, the role of the libero is distinct and comes with specific regulations concerning their identification on the roster. A player designated as a libero is required to have a single, unique number that differentiates them from the other players on the team. This is crucial for officiating purposes, as it allows referees to easily recognize when the libero is on the court and when substitutions occur. Having only one number also simplifies the tracking of individual player statistics, fouls, and rotations for each match.

The rules set by governing bodies like the FIVB (Fédération Internationale de Volleyball) emphasize the importance of a single number for the libero to maintain clarity and standardization in officiating. Players in other positions may have more flexibility regarding roster listings, but the libero’s unique role necessitates a distinct identification system that prohibits the use of multiple numbers on the roster. Therefore, the correct understanding is that a libero can only have one number listed for official purposes.
