Winters (calf) has been ruled out for Sunday's game against the Cardinals, Tommy Yarrish of the Cowboys' official site reports.
Winters has not been cleared to practice since suffering a calf injury against the Packers in Week 6. He'll be sidelined for a second consecutive game, so Shemar James should once again start alongside DeMarvion Overshown at inside linebacker, with Jaishawn Barham providing depth. Winters' next opportunity to play is Week 9 against the Colts on Sunday, Nov. 8.
