Teams MUST have both Players Cards for all players participating and a Roster in order to play an official game. If a team does not have Player Cards (for every player participating) and a Roster, they can still play the game as a friendly, but must forfeit the result in the standings. If both teams fail to have Player Cards and Roster, then it is a double forfeit.
Referees MUST check player cards and roster prior to the game.
Guest players must have a player card and also the Guest Player Roster (click here)
Organizations must use the Affinity System to create Rosters and Player Cards.
