FOX has a doubleheader this week while CBS will show one game to each region.
If you live in the New York area, you will see:
Texans at Packers early on CBS
Rams at Patriots early on FOX
Giants at Steelers late on FOX
The entire nation will see Panthers at Seahawks tonight on NBC and Colts at Jets tomorrow night on ESPN.
If the game you want to see is not being shown in your area, your options are limited due to the lack of out of market options the league has. The out of market package, NFL Sunday Ticket, is only available through DirecTV or a streaming package that can only be purchased if you are a student or unable to subscribe to DirecTV.
