Any active contests where a game is postponed or rescheduled to outside of the original NFL week and to another NFL week will not have its points counted for that original week's bracket.
Our weekly NFL brackets run from Tuesday to Monday.
Any postponed games with originally scheduled dates prior to the contest start time will not be counted towards your score.
When the originally scheduled game and the postponed game are both within the contest's entire duration, the points from those games would be available. In this case, you may need to bench/deactivate certain games to avoid consuming unintended game opportunities.
If a game is postponed and rescheduled within a week where those teams are only playing once, the points would be counted, if you have the players in your lineup.
For details on postponed games in a Tournament contest see: Postponed/Rescheduled Games
For how to bench and activate players see: How do I activate and bench players?
