Games may not be changed or moved, even by mutual consent of the coaches. Games may be moved by the league office in the event that the originally scheduled field is unplayable.
It is your responsibility to check the website several times each week in the Weekly Update section. Any changes for the coming week will be posted there.
If you are the home coach and your field has been changed it is also your responsibility to notify your opponent in a timely fashion. Ask for a confirmation if you are leaving a phone message or sending an email.
In the event of obviously inclement weather (not just a light rain) on a Sunday morning, check the website for field closings. If you are in any doubt about a field being open, call the home team or field contact listed on a map in the book.
