That's a 12th Man flag hanging on the railing behind the goal line of the north end zone at Levi's Stadium here in Santa Clara. And, yes, the Seahawks are in all gray.
The inactives have one semi-surprise: Nickel back Jeremy Lane is out with a gluteus-muscle injury. That means Marcus Burley, back off a hamstring injury, is likely to be inside as the fifth defensive back on passing downs with starting cornerback Byron Maxwell staying outside at corner -- though that could switch with Maxwell inside at nickel and Burley outside depending on matchups with five defensive backs on the field.
Never miss a local story.
As expected, the Seahawks have announced Lemuel Jeanpierre is starting at center instead of Patrick Lewis. Seattle brought back Jeanpierre, injured starter Max Unger's backup the last three years, two weeks ago after giving him an injury settlement in September. Jeanpierre knows line coach Tom Cable's calls and protection audibles; his presence alone could improve the communication issues that have been part of Seattle's pass-protection woes lately.
The other Seahawks inactives: Rookie linebacker Kevin Pierre-Louis (shoulder), reserve linebacker Allen Bradford, Unger, former 49ers defensive tackle Travian Robertson, No. 3 tight end Cooper Helfet (sprained ankle) and reserve TE RaShaun Allen. Defensive end Demarcus Dobbs, another former 49er who was questionable to play because of a sore knee, is active tonight.
The crew of veteran NFL referee Tony Corrente is on tonight's game.
