Games can be rescheduled to another weekend or even on a weeknight, as long as both teams agree to the new time and date. Rescheduled games must fall within the same season. For example, rescheduling a fall season game to January would not be allowed as it falls outside the NPSL season's calendar.
Rescheduling a game to accommodate a coach's schedule is highly discouraged, unless it's done early and has no impact. Teams are encouraged to keep the scheduled game and have an assistant or different coach from the club cover the game. The home team can make the change online by logging on to their team page and updating the game information.
