The libero’s primary job is defense, especially digging and passing. This player will wear a different colored jersey and often times goes in for the middle blockers in the back row. Depending on where you play, the libero may or may not be allowed to serve. The libero is also not allowed to overhand set a front row player in front of the ten-foot line. This player may come out at any time, but before going back in, they must wait for one play.
