Justin Smith out; Trufant, Thurmond won’t play

The Seahawks will not have to deal with Pro Bowl defensive lineman Justin Smith in tonight’s game at CenturyLink Field. Smith got an elbow injury in last week’s game against the Patriots and has been named inactive for tonight’s game.

That’s significant-plus, because Smith is a great player in his own right and has been credited with improving the game of Aldon Smith, who has 19.5 sacks.

Justin Smith had started 185 consecutive games.

For the Seahawks, neither Marcus Trufant nor Walter Thurmond will play because of the hamstring injuries that have sidelined them for three games (Trufant) and last week’s game (Thurmond). Each pacticed on a limited basis Friday, but coach Pete Carroll said they would have to show they could play in pregame warm-ups.

Also, John Moffitt is inactive, so rookie J.R. Sweezy will start at right guard.

Also inactive for the Seahawks:

CB DeShawn Shead

OG Rishaw Johnson

OT Mike Person

DT Jaye Howard

Also inactive for the 49ers:

QB Scott Tolzien

WR A.J. Jenkins

S Trent Robinson

RB Jewel Hampton

LB Clark Haggans

OG Joe Looney
