American Football NCAA Rule 3-3-3-c and d
c. If a game is suspended under Rules 3-3-3-a and b before the end of the fourth period and cannot be resumed, there are four possible options:
1. Resume the game at a later date;
2. Terminate the game with a determined final score;
3. Forfeit of the game; or
4. Declare a no contest.
The option that takes effect shall be determined by conference policy if both institutions are members of the same conference. In nonconference competition, the directors of athletics at the participating institutions or their designees, in consultation with the coaches, must agree on one of the four options. This agreement will include the final score if the game is terminated (Rule 8-1-2). In the event that the directors of athletics do not reach an agreement, the conference policy of the home team shall be used to determine the outcome.
d. If a game is suspended under Rules 3-3-3-a and b after four periods of play and cannot be resumed, the game shall be ruled a tie. The final score shall be the score at the end of the last completed period. (Note: If a winner must be determined in a conference playoff game, conference policy shall determine when and where the game will be resumed.)
