Roster Rules

In collegiate play, if a team cannot field 10 players at the start of a game, they forfeit the game 1-0. If a player is ejected from a game, they are not allowed to reenter the game. Each team is required to have one or more captains on the roster. The captain(s) have official duties for the game, namely calling the coin toss at the start of every game.
