Seattle receiver Mike Williams and Kansas City receiver Dexter McCluster worked out at Qwest Field, but their teams named them inactive. Williams has been Matt Hasselbeck's go-to target for most of the season. Seattle's offense changes quite a bit without him.
Ben Obomanu, Brandon Stokley, Deon Butler, Golden Tate and Ruvell Martin are active at receiver for Seattle. Obomanu and Stokley played particularly well against New Orleans last week. Tate played well against Oakland before suffering an ankle injury. This is his first game back.
Butler will start in Williams' place, the Seahawks said.
McCluster has missed the Chiefs' last four games.
Also inactive for Seattle: fullback Michael Robinson, guard Chester Pitts, defensive end Clifton Geathers, tackle Will Robinson, nose tackle Colin Cole and defensive tackle Amon Gordon. J.P. Losman is the third quarterback.
Also inactive for Kansas City: cornerback Brandon Flowers, safety Donald Washington, running back Tim Castille, safety Jon McGraw, linebacker Charlie Anderson, linebacker Justin Cole and defensive tackle Anthony Toribio.
