As the Cowboys are getting ready their big contest with the Saints, their offensive line is the source of concern on the injury front. Tackle Tyron Smith and guards Xavier Su’a-Filo and Zack Martin have all missed practice time this week. Fortunately, Su’a-Filo and Martin look like they will be able to go, but Tyron Smith is still a question mark. Earlier today Jason Garrett noted he would likely be a game-time decision. If he can’t go, Cam Fleming will have to fill in again after putting in a credible performance against Washington.
