His return was announced as doubtful.
Sherman was on Seattle’s injury report last week because of his Achilles. He was listed as a non-participant all three days, though the team held walkthroughs and his participation was an estimation of what would have occurred in a normal practice.
Sherman has never missed a game since entering the league in 2011.
Injuries have piled up in this game for the Seahawks. Defensive tackle Jarran Reed (hamstring) and left tackle Duane Brown (ankle) both left in the first half. Running back C.J. Prosise (ankle) left in the third quarter.
