The Cowboys placed Anthony Brown (ribs) on injured reserve and called up Eric Smith from the practice squad. With Tyron Smith questionable with a neck injury, the decision to add Smith to the active roster could be viewed as insurance if Smith can't play. Terence Steele started the opener at right tackle for an injured La'el Collins and Brandon Knight can also play tackle. Mike McCarthy prefers not to make two moves for one, which likely means Zack Martin and Connor Williams would stay at guard.
