What happens to an NFL game that is started and suspended? talks about handling suspended games.
Is there a period of time that needs to be played to bring upon an official result? 9:02 of 60:00 of in-game clock may not be enough to determine a winner/loser/tie/no contest upon suspension but suppose a half is played - can a official result be determined by that?
I recall a game in the early 2000s that needed to be finished despite suspension and unruly crowd conditions so I'm inclined to believe that anything less than 60 minutes of in-game clock wouldn't determine an official result.
