The Lions sold 2,000 tickets since yesterday's announcement that 4,500 were left. That number is down to 2,500, allowing the Lions to receive a 24-hour extension to reach a sellout.
The new deadline to get rid of all the tickets to lift the blackout is 1 p.m. on Friday. Typically teams don't get extensions unless a sellout is likely, so this is a very good sign that Sunday's game will be televised locally.
