Dallas cornerback Orlando Scandrick with miss his third straight game with a back injury in what amounts to a playoff elimination game between the Cowboys and Seattle.
Scandrick is inactive for Sunday's game along with defensive lineman David Irving, who had already been declared out for the third straight week with a concussion. Scandrick and Irving were injured in a win over Washington.
Seahawks cornerback DeShawn Shead is active for the first time after spending the season on the physically unable to perform list. Shead sustained a major injury in the playoffs last January.
The Dallas-Seattle winner will still be alive in the playoff race, and the loser will be eliminated.
The Jaguars will be without both starting receivers against the 49ers with Allen Hurns being ruled inactive with ankle injury. Marqise Lee had already been ruled out on Friday with an ankle injury, clearing the way for Dede Westbrook and Keelan Cole to start.
