PHILADELPHIA (AP) -Concerned over their depth at running back with Bran Westbrook recovering from a concussion, the Philadelphia Eagles have signed P.J. Hill off the New Orleans Saints practice squad.

To make room on the 53-man roster for Hill, who was signed Tuesday, the Eagles placed linebacker Omar Gaither on injured reserve with a foot injury, ending his season. Gaither was hurt two weeks ago in the team's loss to the Raiders and underwent surgery last week.

Hill, 5-foot-10, 218 pounds, was signed by the Saints as a rookie free agent out of Wisconsin. He had 26 carries for 128 yards, a 4.9 yards per carry average, and scored three touchdowns in the preseason.

He was among the Saints final cuts before being signed to the team's practice squad.
