On the air: 49ers in Week 13

Posted by ESPN.com's Mike Sando

Ron Pitts, Tony Boselli and Charissa Thompson get the call for Fox when the 49ers visit the Bills in a Week 13 game at Ralph Wilson Stadium. Kickoff is at 1 p.m. ET.

CBS and Fox each have seven crews. The higher-ranked crews draw more attractive assignments such as Super Bowls, playoff games and marquee matchups.
