Cowboys cornerback Mike Jenkins, tight end Jason Witten and receiver Dez Bryant have been limited in practice because of injuries, but are expected to play Sunday against Houston.

Nose tackle Jay Ratliff also was absent Wednesday because he went to be with family following the death of his grandparents last week. He is expected to return Friday and should play against the Texans.

Coach Wade Phillips said Jenkins only has a bruised knee. Witten is recovering from a head injury that Phillips said may be less serious than the club initially thought.

Bryant has a ribs problem sustained in the opener.

Rookie offensive tackle Sam Young practiced for the first time in the regular season. He's been recovering from a knee injury.
