Rules for how postponed games are handled in FanDuel contests vary depending on the sport and contest type. For football contests, you will receive points for any postponed games that are played no later than the next Wednesday.
For one-day baseball, basketball, hockey, or soccer contests, if the postponed game is played on the same day then you will receive points for your players in those games as normal. If a game is postponed to a later date or canceled for any reason, any players you have selected for that game will receive zero points.
For any basketball, baseball, hockey, or soccer contests that are scheduled to include games from multiple days (such as some playoff contests), you will receive points for any games that are played no later than the day after the last game scheduled as part of the contest.
For Slates involving multiple games, if game cancellations and/or postponements mean there is only one game left in a contest, then the contest will be canceled and all entry fees will be refunded.
A game will be considered to be 'played' on a given day if it begins on that day and is completed no later than 6am ET on the following day. For golf contests, postponed rounds will only count if they are completed before the Wednesday following the start of a tournament.
