IRVING, Texas – Running back Lance Dunbar suffered a sprained left foot that could keep him out of the Sept. 8 regular-season opener against the New York Giants.
Dunbar, who is expected to be a big part of the offense as a third-down back, is in a protective boot and could need 3-4 weeks to return, according to a source. Dunbar had a 43-yard catch against Arizona on Saturday but fumbled at the end of the play. He returned to the game and did not mention being hurt in the locker room after the 12-7 loss to the Cardinals.
Wide receiver Cole Beasley suffered a sprained foot on Aug. 9 at Oakland and has yet to return to practice. Running back DeMarco Murray missed six games last year with a sprained foot.
The Cowboys welcomed back guards Kevin Kowalski (knee) and Ray Dominguez (shoulder) to the practice field, increasing their interior line depth.
Rookie safety J.J. Wilcox remains away from the team following the death of his mother last week in Cairo, Ga.
Also sitting out: Morris Claiborne (knee), Matt Johnson (foot), Eric Frampton (calf), Ernie Sims (groin), Alex Albright (impending back surgery), Toby Jackson (groin), Anthony Spencer, Travis Chappelear, Jay Ratliff, Beasley, Ryan Cook (back), Ronald Leary (knee) and Nate Livings (knee).
