The NFL announced its schedule today; here is the list of Sundays where Fox has scheduled doubleheaders (except when the Sunday schedule would be pre-empted for post-season baseball). On Fox doubleheader days, every Fox station (except for a few in NFL cities, because of the strange blackout rules) has a game that starts at 4:15 Eastern - and when that game ends, Fox will switch to another in progress until all of its 4:15 games (Fox shows games where the visiting team is an NFC team) are finished. Of course, for KOTH fans, this almost always means the episode is shown "already in progress" in the Eastern and Central time zones, and on occasion an episode will be pre-empted; a couple of times last year, the games lasted so long that the start of that night's Simpsons episode was delayed.
9/10 - 3 late games on Fox 9/24 - 3 late games 11/12 - *2 late games 11/26 - *no late games scheduled 12/17 - *2 late games 12/31 - *2 late games
*Starting in November, one game per week scheduled for Sunday afternoon will be moved to Sunday night, and each network can move one of its 1:00 games to 4:15 each week. Because of this, the number of late games can be one higher or lower than listed. (The announcement of which games are moved each week is supposed be on the Tuesday two weeks before the Sunday involved.)
