The league has a policy requiring all NFL games not sold out 72 hours before kickoff to be blacked out in the local television market.
According to the NFL, this includes all television signals within a 75-mile radius of the stadium and those areas with a television signal within the 75-mile zone.
Chargers officials said nearly 5,600 general tickets remain for the game at Qualcomm Stadium. Normally the Cowboys draw a good portion of their fans to away games, especially in San Diego.
Of course, the game will be telecast in the Dallas/Fort Worth area without restrictions.
