Mike Jenkins (back) among Cowboys inactives

PHILADELPHIA -- Cornerback Mike Jenkins is inactive after missing the last two days of practice due to a back injury.

The Cowboys promoted cornerback Vince Agnew off the practice squad Saturday to prepare for Jenkins' absence.

The other inactive Cowboys are running back DeMarco Murray, safety Matt Johnson, linebacker Dan Connor, guard/center David Arkin, center Phil Costa and defensive lineman Sean Lissemore.

With Arkin inactive, right guard Mackenzy Bernadeau would move over to center if fill-in starter Ryan Cook gets injured.
