Admin February 6, 2020 The libero in volleyball is the player that wears a different color jersey than their colleagues. The libero is a specifically designated player who may replace any player in the back row without requiring a substitution. They might never play in the front row again. However, when a player comes off the bench to play libero, that player must also wear the same color jersey as the starting libero. As a result, some leagues mandate all potential liberos to wear their alternate jersey even when sitting on the bench.
