SEATTLE -- The St. Louis Rams' inactive list could favor the Seattle Seahawks' run defense.

The Rams will be without veteran defensive tackle Fred Robbins, who was questionable on the injury report and did not practice during the week. Robbins' absence means more playing time for Darell Scott and Gary Gibson.

Also inactive for the Rams: quarterback A.J. Feeley, quarterback Tom Brandstater, running back Quinn Porter, fullback Brit Miller, linebacker Justin Cole and guard Kevin Hughes. Kellen Clemens will serve as the backup quarterback to Sam Bradford.

For Seattle, linebacker David Hawthorne is active. The Seahawks' inactive list features quarterback Josh Portis, safety Jeron Johnson, cornerback Kennard Cox, linebacker Adrian Moten, guard Mike Gibson, guard Paul Fanaika and defensive tackle Pep Levingston.
