The Cowboys added starting safety Byron Jones to their injury report Thursday. Jones has a groin injury.
The third-year veteran, a former first-round draft choice, has never missed a game. He played all 57 defensive snaps in the season opener.
Jones is one of four defensive backs on the team’s injury report.
Cornerback Jourdan Lewis was inactive last week with a hamstring injury but has practiced in full both days this week. Cornerback Chidobe Awuzie, who played 39 snaps in his debut, also was a full participant with an ankle injury. The Cowboys likely will need both this week.
Starting cornerback Orlando Scandrick had surgery Monday for a broken left hand and has missed practice this week. When Scandrick left Sunday’s game, Anthony Brown replaced him. Brown moved to the slot in nickel packages, with Awuzie outside.
