SAN JOSE -- If you have DirecTV and were hoping to watch football on the Pac-12 Networks, you're out of luck.

The conference won't reach a carriage agreement with the nation's largest satellite operator before the season starts Thursday, according to a source.

There are six football games scheduled for broadcast on the Pac-12 Networks this weekend, including San Jose State at Stanford on Friday at 7 p.m. and Nevada at Cal at noon Saturday.

Scheduled for Thursday are Northern Colorado at Utah at 4:15 p.m. and Northern Arizona at Arizona State at 7:30 p.m.

In the Bay Area, the Pac-12 Networks are available on Comcast, Wave/Astound and San Bruno Cable.
