A libero is a specialized position in the sport of volleyball. This player is primarily responsible for defensive skills, particularly receiving serves and digging attacks from opponents. The libero wears a different color jersey and cannot attack the ball above the net's height. They also cannot serve, block, or attempt to block. The libero plays a crucial role in enhancing the team's defense and is allowed to substitute in and out of the game without restrictions. This flexibility helps maintain a strong defensive presence on the court, allowing other players to focus on offensive strategies.
