Cowboys' Jeremy Mincey out against Falcons with concussion

IRVING, Texas (AP) Dallas defensive end Jeremy Mincey has been ruled out of the Cowboys' game Sunday against Atlanta because of a concussion.

Mincey was a limited participant in practice Thursday and didn't work out Friday. The 10th-year player dealt with concussion symptoms last season as well.

As expected, rookie defensive end Randy Gregory is out again with a sprained right ankle. He sat last week at Philadelphia after getting injured in the opener against the New York Giants.

The loss of Mincey hurts Dallas' depth in trying to pressure Falcons quarterback Matt Ryan, the NFC leader with 661 yards passing.

Tight end Jason Witten is probable with two sprained ankles and a sprained left knee. He was a full participant Friday after being limited the first two practice days.

Guard Ron Leary (groin) is questionable.
