The Dallas Cowboys have an offensive line concern heading into the halftime break. CBS Sports’ Tracey Wolfson reported that the one backup offensive lineman who is starting is undergoing x-rays.

Dallas has been without starting left guard Tyler Smith through both games as he nurses a hamstring injury suffered early in the practice week ahead of the season opener. He was replaced in the starting lineup by Chuma Edoga, a free agent pickup this offseason, formerly of the New York Jets. Edoga left the first half early to get his elbow looked at.

Filling in for him is UDFA rookie T.J. Bass, who took the last snap of the half, a kneel down with Dallas leading 18-10.
