Skelton is getting the start for Arizona while Kevin Kolb continues his recovery from a concussion suffered against San Francisco last week. It's possible all four Week 15 games involving NFC West teams will feature at least one backup:
St. Louis vs. Cincinnati: Kellen Clemens is expected to start for the injured Sam Bradford behind center for the Rams. Clemens was not even on the Rams' roster until the last couple of weeks. Bradford's injured ankle had him back in a walking boot and missing practices. He's doubtful.
Arizona vs. Cleveland: Skelton gets the start for Kolb. NFC West alumnus Seneca Wallace starts for the Browns' injured Colt McCoy. Skelton has done a good job picking up yardage with his feet. He's big, strong and tough to take down. Wallace is fast and athletic enough to moonlight at wide receiver as needed.
San Francisco vs. Pittsburgh: Nothing seems to keep the Steelers' Ben Roethlisberger from playing. He practiced on a limited basis Friday after resting his injured ankle previously during the week. Charlie Batch would start for Roethlisberger on Monday night, if needed.
Consider it a testament to Tarvaris Jackson's toughness and recuperative powers for his injury status to barely merit a mention. Seattle's starter suffered a partially torn pectoral muscle in Week 5 and missed only one game.
