A pair of St. Louis Rams unexpectedly returned to practice on Thursday. Jason Sehorn hit the practice field for the first time in three weeks, even though an x-ray earlier this week showed his broken left foot had not completely healed. Sehorn saw limited work on Thursday. Turley, meanwhile, came back a day early. He’s coming off a concussion suffered in the fourth quarter of Sunday’s win over the Packers. Head coach Mike Martz expects Turley to be cleared today, meaning he’ll be in the lineup on Sunday at Pittsburgh.
