I don't think that CBS will air this game in many markets. Probably Green Bay and South Flordia. it is a 1-5 team vs. 1-4 team.
Living in Philadelphia, i know how sad it is, to never see the dolphins on tv.
I highly recommend getting Direct TV and the sunday ticket. For the last 3 years i've watched them on nfl.com, just the cheesy game tracker they have, I know it's horrible and super lame, and your eyes really hurt for staring like a zombie at the thing waiting for it to load the next play.
I used to listen to the games on NFL.COM for free before that. But of course they charge money for that now.
I'm going to the game this sunday, my first game ever.
GO DOLPHINS!
