Football governing bodies may provide further instruction to referees on administering quick free kicks; for example, the United States Soccer Federation advises that referees should not allow a quick free kick if a card is shown prior to the restart, if a trainer has to enter the field to attend to an injured player, if the kicking team requests enforcement of the 9 meters rule, or if the referee needs to slow the pace of the match (e.g., to talk to a player).
