The short answer - probably. This is a Fox doubleheader weekend. All of the normal Sunday afternoon games are on Saturday this year - NFL custom when Chriatmas Day is on Sunday. The only Sunday game is the NBC night game.
Most of the country is getting the Giants-Jets early, and the Eagles-Cowboys late. We get Joe, Troy, and Pam at Cowboys Stadium.
The only other late game on Fox is the SF-Sea game, and the only markets scheduled for that game instead are all on the West Coast.
The only exception is that New Orleans has switched, and is now showing the 49ers-Seahawks. I guess that's because of the competition for the #2 and #3 seeds, and Saints fans want to follow the 49er game.
So, unless you are in New Orleans market, any market in Oregon, Washington, or northern California (north of Bakersfield and Santa Barbara), you will get the Cowboys on your local Fox station, and won't have to resort to a bootleg internet stream. Los Angeles and San Diego markets are getting the Cowboys.
Go, Cowboys! Fear the Star!
