From Dallas Cowboys
IRVING (AP) 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 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 dropped LB-FB Isaiah Greenhouse from the practice squad.
