Player not on Roster

[FMadera]

Coach would have to change the roster, which would be a penalty of a loss of rally. Player would now be able to play.

On a side note, I'm not sure why coach would scratch her in the first place. There's no rule that states that a player on the roster would need to be there during warmups, so in this situation, had the coach just left the player on the roster, there would be no need for another roster change.
