I live in the Knoxville area and noticed last night I could not get any of the games and only was able to see the UT game this afternoon. The message states that it is due to their blackout policy. Was never an issue with Comcast.
I don't live in the Knoxville area, but do you know if Direct will carry the SEC Network, I live in the middle Tennessee area, the game was a blackout on espnu, but we got it on a local channel 30, did you check your local channels.
I have it with Charter. Probably another reason my cable bill is ridiculous. RedZone only good thing about the NFL network.
