Rams center out with knee injury

St. Louis Rams center Jason Brown has been helped off the field favoring his right knee at the two-minute warning against the Seattle Seahawks. The team said Brown’s return is questionable.

The Rams began Sunday’s game without two other offensive line starters, tackle Jason Smith (concussion) and guard Richie Incognito (foot). Brown apparently was injured falling backward over teammate Jacob Bell.

Mark Setterstrom, who started his first game since 2007 at guard, moved to center after Brown was hurt. John Greco replaced Setterstrom at guard.
