IRVING, Texas -- Cowboys cornerback Brandon Carr missed Thursday's practice with an undisclosed illness.
The Cowboys are already down a corner because Morris Claiborne is out with a hamstring injury.
Defensive end DeMarcus Ware (back) returned to practice Thursday after missing Wednesday's session. Coach Jason Garrett said Ware's back problem wasn't considered serious.
Fellow starting defensive end George Selvie returned to practice too, after missing practice with a tight back.
