I know it's a preseason game, but in Chicago last night the Colts game was NOT on NFL network. Instead it was the Cowboys - Vikings game.

This confused me greatly as the NFL network is a national network. Similar to ESPN, CNN, etc. what's being shown on those networks is what the entire country will see.

Did anyone else have this problem? Or was it only in Chicago? This probably won't happen during the regular season since there aren't multiple Thursday night games, but  what happened here?

At least the preseason is over and we can get on with the show.
