Cowboys sign RB to practice squad

IRVING, Texas -- With injuries to DeMarco Murray and Lance Dunbar, the Dallas Cowboys signed running back Davin Meggett to the practice squad.

Murray is not expected to play Sunday against the Philadelphia Eagles because of a sprained medial collateral ligament in his left knee. Dunbar missed the Washington Redskins' game with a hamstring injury and was unsure he would be able to practice this week.

Rookie Joseph Randle and Phillip Tanner are the only healthy running backs on the 53-man roster. Randle is expected to get the bulk of the work in Murray's absence. He had 11 carries for 17 yards and a touchdown against Washington.

Meggett was with the Indianapolis Colts in the summer but was cut in August. He was with the Houston Texans for a time in 2012. The son of former NFL running back Dave Meggett ran for 2,411 yards at Maryland.

It is possible he could be a late-week call up to the active roster if the Cowboys want to have a third runner on the game-day roster.
