The NFL has announced that they’ve moved back the kickoff times for all 4:15pm EST games to 4:25pm EST for the upcoming season.
The NFL only schedules 4:15 games when they’re a part of a double-header on FOX or CBS. Any game that isn’t a double-header is scheduled to begin at 4:05pm EST. The 4:05pm games that aren’t a part of a double-header will remain at that time.
The reason the NFL has decided to move back the 4:15 double-headers, is to 4:25 is to prevent any over lapping from the 1pm games.
