Cowboys linebacker Justin Durant out 3-4 weeks

The Dallas Cowboys thin defense has gotten thinner. Linebacker Justin Durant will miss the next 3-4 weeks with a groin injury suffered in Week 1.

Kyle Wilber is expected to fill in for Durant who had been named a defensive captain in the wake of middle linebacker Sean Lee going down during training camp.

Durant missed six games last season with a hamstring injury. The Cowboys are at Tennessee this Sunday.
