Starting middle linebacker Sean Lee, who just returned after missing the previous two games with a hamstring injury, left in the third quarter with a neck injury. Team officials said Lee will not return. Ernie Sims replaced Lee in the base defense.
Wide receiver Dwayne Harris, who also returned to the field after missing the Thanksgiving Day game against Oakland with a hamstring injury, re-aggravated the injury in the third quarter. Terrance Williams returned a kickoff after the Bears moved ahead to a 35-14 lead.
Weakside linebacker Bruce Carter injured a hamstring, also in the third quarter and his return was questionable. But on a cold night, the coldest game in Cowboys' regular season history, it appears doubtful he will return.
