Cowboys left guard Kyle Kosier injured his right knee in the fourth quarter Sunday. It's the same knee he sprained the medial collateral ligament in during training camp. Kosier was injured Aug. 18 and returned to practice Sept. 15, missing the season opener at Washington.
Kosier will have an MRI on Monday to determine the extent of the injury. The Cowboys have a bye next Sunday.
Montrae Holland replaced Kosier in the lineup.
