Cowboys LG Kyle Kosier sprains knee
Kosier was replaced in the lineup by Montrae Holland.
It's the second time this year Kosier injured his right knee. He suffered a sprained MCL in mid-August and missed the regular-season opener at Washington. He made his season debut last week against Chicago.
Kosier will undergo an MRI exam Monday to determine the extent of his injury. The Cowboys are off next week.
Jenkins had an interception and Witten led the team in catches with seven for 56 yards.
Rookie wide receiver Dez Bryant, who was limited in practice this week because of sore ribs, also played and had no problems. Bryant had four catches for 50 yards.
