Cowboys backup guard Ajani Cornelius limited in practice with knee injury

The Dallas Cowboys listed backup right guard Ajani Cornelius as a limited participant in Wednesday's practice due to a knee injury. His status follows the team placing starting left guard Tyler Smith on injured reserve after he underwent thumb surgery this week. T.J. Bass is slated to start at left guard in Smith's absence. To address depth concerns on the offensive line, the team signed Nick Leverett from the practice squad and added veteran Laken Tomlinson to the practice squad. Elsewhere on the injury front, defensive tackle Jonathan Bullard participated fully despite a groin issue. Practice squad quarterback Joe Milton was absent from the session with an excused leave.
