SAN DIEGO -- The San Diego Chargers say their home opener Sunday against the Jacksonville Jaguars will be blacked out on local TV because they fell more than 7,000 tickets short of reaching a sellout.

The Chargers had a streak of 48 straight sellouts, playoffs included. The last Chargers game blacked out was against New Orleans on Nov. 11, 2004.

The Chargers, Southern California's only NFL team, say other games are in danger of being blacked out this season. They say more than 12,000 tickets remain for their next home game against Arizona on Oct. 3.

Games need to be sold out 72 hours before kickoff to avoid a blackout in a 75-mile radius.

Also, the Oakland Raiders' home opener against the St. Louis Rams on Sunday will be blacked out.

The Raiders haven't sold out a game since last year's season opener against San Diego. They have had eight straight blackouts since that game.

Oakland has had 77 of 121 regular-season home games blacked out since moving back from Los Angeles for the 1995 season. This will be Oakland's first home opener since 2004 against Buffalo that will be blacked out locally.

The NFL has given the Detroit Lions a 24-hour extension to sell out its home opener against the Philadelphia Eagles and avoid a local television blackout.

The team announced Thursday it has to sell 2,000 tickets by 1 p.m. EDT to ensure the game will air on local television. The game will not be shown in the Detroit, Lansing, Saginaw-Flint and Toledo, Ohio, markets if all of those tickets are not sold by the deadline.

Detroit sold out four of its eight home games last year despite winning just twice. In 2008, the Lions became the first NFL team to have an 0-16 season.

The Lions also had some of their smallest crowds in two decades, announcing some that were just larger than 40,000.
