Tackle Tyron Smith did not practice Thursday because of a neck injury, however, a source said Smith is expected to be good for Sunday vs. Atlanta. Smith was on the practice field during the open portion of work to the media and appeared to go through some individual work. He has missed three games in each of the last in each of the last four seasons. Rookie Terence Steele will start in right tackle for La'el Collins, who is on IR. On Tuesday, backup OT Cameron Erving (knee) was placed on IR.
