It is the referee's responsibility to determine whether play should be stopped immediately. The most common injury in youth soccer is damage to a player's pride. Nobody likes to fall down, even if it was someone else's fault, and especially if it is one's own fault. Loud criticism of the officials is not part of the game of soccer. Yes, coaches, and even parents, can be sent off if violating this concept.
AYSO philosophy encourages positive comments and coaching.
Think twice about criticism of players' actions. Turn critical remarks into positive comments. During the regular season, matches can end in a tie. There is no overtime. Only during tournament play will there be overtime and, if necessary, a shoot-out.
