Cowboys add journeyman CB Walker

The Dallas Cowboys have signed journeyman Frank Walker to
bolster a depleted corps of cornerbacks.

Orlando Scandrick is expected to miss at least the upcoming game
at San Francisco because of an ankle injury, and Terence Newman has
been sidelined since early in training camp because of a groin
injury. Mike Jenkins was in and out of the opener because of a
variety of injuries, leaving Dallas down to its fourth- and
fifth-stringers, plus a backup safety.

Walker has played in 93 games over an eight-year career with the
Giants, Packers, Ravens and Vikings. He went to training camp with
the Titans.

To make room for Walker, Dallas released tight end Martin
Rucker. The Cowboys also released receiver Laurent Robinson,
re-signed fullback Tony Fiammetta, and dropped LB-FB Isaiah
Greenhouse from the practice squad.
