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.
For any teams that have two games in the same NFL week, only the originally scheduled game's points will be counted towards your overall scoring.
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 players in your roster.
