Steve Smith missed practice again Thursday and remains questionable for the season opener against Atlanta. "Right now it's day-to-day and when it comes down to Sunday it will be a game-day decision," coach John Fox said. Smith was limited to 10 practices in the preseason because of a strained left hamstring and an ingrown toenail that required stitches. He did not play in any of Carolina's four preseason games. Smith then tweaked his right hamstring in practice Tuesday and was held out of Wednesday's workout.
