Cowboys starting left guard Tyler Smith left practice early Monday.
Multiple reports indicate Smith experienced hamstring “discomfort,” and the Cowboys believe it is a minor issue.
He spoke to head athletic trainer Jim Maurer before leaving the field for examination.
The Cowboys do not practice again until Wednesday.
Smith, a first-round pick in 2022, played 1,022 snaps at left tackle and 121 at left guard last season as a rookie. The Cowboys list rookie Asim Richards as Smith’s backup, but veteran Chuma Edoga would be the more likely option if Smith were unable to play.
