It appears WWJTV won't be showing the Lions-Browns game until 8 p.m. ET (coverage begins at 7).  Although the game starts at 4 p.m., there is a delay on when it is being shown.  I don't know if that is because the game is blacked out or if WWJTV didn't want to interrupt CBS' golf coverage, but either way, the game won't be on until tonight.

UPDATE: The game is being broadcast live on the NFL Network in some places, so if you don't want to wait until tonight you may be able to watch it right now.
