The Dallas Cowboys offensive line looks dazed and confused trying to protect a non-mobile quarterback, and things may be getting worse. As Andy Dalton is being besieged by blitzes and pressure from all angles, the Cowboys stalwart right guard could be missing on their next drive.

According to Cowboys sideline reporter Kristi Scales, Zack Martin is being evaluated for a shoulder stinger.

Martin came back for the next drive, but was slumped on the ground after the first play. Second-year guard Connor McGovern is in the game to replace him.

According to Scales, Martin is being evaluated for cognitive reasons.

The Cowboys are playing the rest of the season without tackles Tyron Smith and La’el Collins, and center Travis Frederick retired in the offseason. This is not the Great Wall of Dallas anymore.
