While the deadline to have a blackout lifted is today at 1 p.m., the Lions have been granted a 24-hour extension, pushing the deadline back to Friday afternoon. Anytime an extension is granted, a sellout is basically guaranteed to happen, so the game should not be blacked out.
I will say, though, it's disappointing that it had to come to this for the home opener. I figured the first game at Ford Field would sellout without an extension, but as it turns out, the Lions are struggling to get rid of all the tickets. That certainly doesn't bode well for the rest of the season, but I guess I should just be happy that Sunday's game will likely be shown on TV locally.
