The Dallas Cowboys are managing multiple roster changes and injuries ahead of their season opener against the New York Giants. Pro Bowl guard Tyler Smith was placed on injured reserve following thumb surgery, with an expected absence of at least four to six weeks.

To mitigate the loss of Smith, the team elevated T. J. Bass to the starting left guard position and promoted Nick Leverett from the practice squad to the 53-man roster. Additionally, the team signed veteran interior offensive lineman Laken Tomlinson to the practice squad.

Other injury concerns include tight end Luke Schoonmaker, who was listed as a non-participant for personal reasons, and offensive lineman Ajani Cornelius, who was limited in practice due to a knee injury. Defensive lineman Jonathan Bullard participated fully despite a groin issue.
