Seahawks release WR to activate Irvin

INDIANAPOLIS -- In a bit of a surprise move, the Seattle Seahawks released wide receiver Stephen Williams Saturday in order to place linebacker Bruce Irvin back on the active roster.

It’s no surprise that Irvin was activated after a four-week suspension for performance enhancing drugs. But releasing Williams means Seattle enters Sunday game against the Indianapolis Colts with only four wide receivers -- Golden Tate, Doug Baldwin, Sidney Rice and Jermaine Kearse.

Williams was signed in the offseason as a free agent who spent two seasons with the Arizona Cardinals. Williams, 27, had a strong preseason with three long touchdown receptions that showcased his speed and his ability to outjump defenders for the ball by using his 6-foot-5 frame. But Williams did not have a catch in the first four games and didn’t help much on special teams.

The fact that Seattle did not release an offensive lineman (10 are on the active roster) may mean that starting center Max Unger isn’t likely to play Sunday. Unger, who missed last week’s game with a triceps injury, is listed as questionable. Seahawks coach Pete Carroll said Friday that Unger, along with tight end Zach Miller (hamstring), would be game-time decisions.
