Jones has been unable to practice all week after suffering the injury against the San Francisco 49ers last Thursday night. Jones has 2½ sacks on the season primarily as a situational pass rusher. If he's unable to play, rookie Greg Scruggs will pick up the additional workload for Seattle. Scruggs earned his first career sack last week against the 49ers.
Receiver Doug Baldwin (ankle) and cornerback Byron Maxwell (hamstring) have been ruled out. Guard John Moffitt is listed as questionable with a knee injury but isn't expected to start even if he's able to play. Moffitt has missed the last four games.
