ARLINGTON, Texas -- Here we go again.
Oft-injured offensive lineman T.J. Lang has been knocked out of Sunday's game against Dallas with a concussion. He suffered the injury when he collided with Cowboys linebacker Jaylon Smith in the first quarter.
He was replaced at right guard by Kenny Wiggins, who actually played well in a spot start for Lang back in Week 2 against San Francisco. Still, injuries continue to derail Lang's progress as well as the consistency of the offensive line.
Lang missed games last year with brain, back and foot injuries, and was limited in several others.
