This week FOX has a doubleheader while CBS will show a single game to each region. However, New York only has a single FOX game due to league rules. The Giants play a home game in the early timeslot being shown on CBS. When a local team plays at home no other game may be shown simultaneously. (There are a few exceptions, but none apply in this case.) That means no early FOX game in New York and no doubleheader.
