ST. LOUIS (AP) - Center Scott Wells' return after breaking his foot in the season opener figures to strengthen the St. Louis Rams' offensive line at two spots.

Robert Turner has been consistent as the stand-in starter for nine games and could start at left guard this week at Arizona. He's been a take-charge guy from the start, carrying his blocks downfield and usually showing up first after the tackle to keep the pile clean and give his running back a helping hand.

Turner's versatility on the line was a plus when the Rams (3-6-1) signed him to a one-year, low-budget free agent deal as a high-quality backup at center and guard. Familiarity with offensive coordinator Brian Schottenheimer from when both were with the New York Jets didn't hurt, either.

Turner, who started the opener at left guard, and right guard Harvey Dahl are the only linemen who have started every game. Turner could replace Shelley Smith, who has made the last four starts at left guard but has struggled lately.
