NFL extends Cardinals' blackout deadline 24 hours

Nov 12, 2009 - 10:05 PM TEMPE, Ariz.(AP) -- The NFL has given the Arizona Cardinals a 24-hour extension to the television blackout deadline for Sunday's game in Glendale against the Seattle Seahawks.

To air live on local television, league rules require games to be sold out 72 hours before kickoff. This is the fourth time this season the NFL has granted Arizona an extension.

As of Thursday afternoon, the Cardinals say they have about 800 tickets remaining to sell before Friday's new deadline of 2:15 p.m. local time.

The Cardinals have sold out all 38 games played at University of Phoenix Stadium, which opened in 2006.
