St. Louis Rams center Scott Wells sustained a foot injury on Sunday against the Lions and the team is calling his return questionable. Robert Turner moved over from guard to replace Wells at center, and rookie Rokevious Watkins came on to replace Turner.

Wells was the big offseason acquisition for the Rams, signing a four-year, $24 million deal. He was expected to anchor the center of the offensive line but he was injured throughout the Rams' offseason program and training camp. The foot injury now appears to be a separate issue. His absence will add increased pressure on the Rams offensive front, which is dealing with the Lions touted interior led by Ndamukong Suh and Nick Fairley.

The defense has kept the Rams in the game so far with three huge first-half interceptions but the Lions evened things up in a relatively uneventful third quarter. A Scott Hanson field goal knotted things at 13-13.
