National Federation Rule 7-1-3 –
a. In the event a game must be suspended because of conditions (darkness, weather, etc.) which make it impossible to continue play, the head referee shall declare it an official game if one complete half or more of the game has been played. If less than one-half of the game has been played, the game may be continued from the point of interruption at the next available playing time; that is, a delay may be called or a game suspended until rescheduled.
b. Suspended IHSAA Tournament Games – when weather, darkness or similar conditions cause a game to be called before it is a regulation tournament game, it shall be considered a suspended game and shall be continued from point of suspension at a later date. Such IHSAA tournament series games must be rescheduled for the following playable date and should take precedence.
The assigned tournament game officials should work in conjunction with the IHSAA Tournament Site Manger to make all decisions about suspended contests, restarting a suspended contest and rescheduling a suspended contest.
