IRVING, Texas — The Dallas Cowboys will be without safety Ken Hamlin at least three weeks and offensive tackle Marc Columbo longer than that.

Hamlin sprained an ankle and Columbo broke his left leg and sustained ankle ligament damage in Sunday’s 17-7 loss to the Green Bay Packers.
Cowboys coach Wade Phillips said Hamlin’s high ankle sprain will sideline him 3-4 weeks. Phillips wouldn’t rule out a late-season return by Columbo, who had surgery Monday.
Cornerback Mike Jenkins severely bruised an arm muscle against the Packers but is expected to play Sunday against the Washington Redskins.
