The good news for Byron Jones is the league didn’t fine him for an unnecessary roughness penalty he had against the Chargers last week. The bad news for Jones is the former first-round pick is seeing his play time diminish. The Cowboys made changes in their secondary for Thursday’s game against Washington. They benched cornerback Anthony Brown, replacing him with rookie Chidobe Awuzie, who had three tackles and three pass breakups and didn’t allow a reception against him. Brown’s only playing time on defense Thursday came when he filled in for the injured Orlando Scandrick. Brown played the final eight defensive snaps and made an interception, a tackle and a pass breakup. The Cowboys also gave rookie Xavier Woods more playing time, alternating him with Jones at free safety. Woods played 46 of 60 snaps and Jones 45. Woods had six tackles, including one for loss, and Jones had four tackles.
