When are rosters and lineups due, and what are the penalties if they're late or wrong?

Question

Accepted Answer

Rosters All teammates must be listed. The roster is due at the prematch conference. Submitting it later is an unnecessary delay (administrative yellow card). Roster changes may be made until 10 minutes remain on the pregame clock. After that, a roster violation or added player results in a loss of rally/point to the opponent. Lineups Due First set 2 minutes before the end of the timed warm-up Later sets No later than 1 minute remaining in the timed interval between sets Late lineup: not in at those times = unnecessary delay, yellow card warning. Still not in by the end of the warm-up or interval = unnecessary delay, red card penalty. A lineup submitted early may be changed up to the 2-minute mark before the first set, and up to the 1-minute mark before later sets. After that, changes must be made by substitution. Duplicate numbers in the starting lineup: the team must use a substitution to change one of them. Libero number listed as a starter: change the libero to a different legal number, or use a substitution to put a different legal number in that position. Mark the libero's number on the lineup sheet for each set if one is used.
