Cardinals need to sell 1,000 tickets

TEMPE, Ariz. -- The NFL has given the Arizona Cardinals a 24-hour extension to the television blackout deadline for Sunday's game in Glendale against the Carolina Panthers.

The Detroit Lions game against the St. Louis Rams will be blacked out on TV in and around the Motor City.

Lions spokesman Bill Keenist said Thursday the team did not sell all the 10,000-plus tickets that were still available the previous day.

In order to air live on local television, league rules require games to be sold out 72 hours prior to kickoff.

Arizona's blackout deadline has now been extended until 2:15 p.m. local time Friday.

As of Thursday afternoon, the Cardinals say they have about 1,000 tickets remaining to be sold.

The Cardinals have sold out all 37 games played at University of Phoenix Stadium, which opened in 2006.

However, this is the third time this season that Arizona has needed a 24-hour blackout deadline extension from the league.

Detroit sold out two of its first four games, getting a lot of help the last time it was home from Pittsburgh Steelers fans who filled Ford Field.
