Players on the restraining lines are still permitted to move behind the restraining lines when the whistle blows, but they are not permitted to cross until they here “Possession!”


Kicking The Ball

Players are now permitted to kick the ball as part of field play on any non-shooting effort.   Kicking the ball into the goal is NOT permitted.


All coaches have complete responsibility for the conduct of their players, substitutes and spectators at all times. Coaching from the sidelines (giving direction to one’s own team on points of strategy and position) is encouraged, providing:

  • Each coach or substitute remains on their own half of the field between the substitution area and the restraining line.
  • No coach, substitute or spectator makes derogatory remarks or gestures to the umpires, other coaches, players, substitutes, or spectators.
  • No coach, substitute, or spectator uses profanity, participates in or incites any manner or disruptive behavior.
  • Officials have the right to stop a game at any time and to eject a coach based on their behavior, and the behavior of fans or players.
    All ejections will be at the discretion of the tournament directors and their decision will be final.


Inclement Weather Policy

  • We will play rain or shine. The fields are turf, so they will not close.
  • In case of thunder/lightning, all games will be suspended and fields will be cleared by sounding an air horn (three long blasts).
  • Games will resume 30 minutes after the last thunder/bolt was heard/seen.
  • Games will resume according to the actual time of the day – missed time/games will not be made up. Scores will be recorded as they stood when game ended as long as teams played at least 10 minutes.
  • Cancellation of the games is at the discretion of site managers, tournament directors and officials. Keeping everyone safe is our first concern. Partial refunds due to inclement weather are at the discretion of the tournament directors.
