The Bengals announced Thursday that they failed to sell out a game 72 hours in advance for the first time since Nov. 9, 2003. Under NFL policy, that means no television of the game in the Bengals' home markets of Cincinnati, Dayton and Lexington, Ky.
The Bengals had sold out 57 straight games.
The Jacksonville Jaguars were luckier, getting a 24-hour extension to avoid the blackout.
The Jaguars have until 1 p.m. ET Friday to sell enough tickets for the blackout to be lifted, and Sunday's game against Cleveland to be televised locally and in secondary markets.
Jacksonville, which blacked out nine of 10 home games last season, sold enough tickets to its first five home games to avoid any blackouts. The small-market franchise didn't even have to request an extension until this week.
The club needs to sell about 3,000 nonpremium tickets to avoid a blackout.
The Jaguars (5-4) are a game out of first place in the AFC South and are coming off one of the most exciting finishes in team history -- Mike Thomas' 50-yard reception on the final play to beat Houston.
