The Arizona Cardinals have avoided a blackout. By selling enough tickets the Cardinals game against the San Francisco 49ers tomorrow at 1:15 p.m. will be televised on Channel 10. The Cardinals announced the sellout Friday. Teams have until 72 hours before kickoff to sell out and avoid a local TV blackout, but the NFL granted the Cardinals a one-day extension. This will be the Cardinals' 35th consecutive sellout since moving into University of Phoenix Stadium.
