Number of players and substitution
No team may use more than 18 players in a match, 11 players on the field and 7 substitutes. A substituted player may reenter in the match. Substitutions can be done without stopping the game. Notice that the game has to be stopped and the referee has to be informed at the substitution of a goalkeeper. All substitutions should be done within the technical area of the team. If there is no technical area the substitution should be made at the centre line. The player that will be substituted has to leave the field before the new player can enter the field. Incorrect substitutions will be punished with a yellow card.
In classes B12, B11, G12 and G11 it is allowed to have an unlimited number of players during a single match, but only 7 can be on the playing field simultaneously.

This player has to be on the participant list of all teams he/she will play for.The player must also be present during the age control for each team the player plays for. There is no maximum number of players on the participant list.
