TEMPE, Ariz. -- The NFL has given the Arizona Cardinals a 24-hour extension to the television blackout deadline for Sunday's home game against the Houston Texans.
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 11:15 a.m. ET Friday.
As of Thursday afternoon, the Cardinals said they have just under 1,000 tickets remaining to be sold.
The Cardinals have sold out all 36 games played at University of Phoenix Stadium, which opened in 2006.
