Following their road win over the Dolphins, the Cowboys traveled to Soldier Field to play a Sunday night match with the defending NFC Champion Bears.  The game was close early as the Bears' Robbie Gould and the Cowboys' Nick Folk each hit field goals respectively to make it a 3-3 tie at halftime.  The Cowboys took the opening drive of the third quarter and ended it with a Tony Romo to Jason Witten touchdown pass.  The Bears responded on the ensuing drive with a Cedric Benson goal line plunge.  The Cowboys struck again before the end of the third quarter, Romo connecting on his second touchdown pass, this time to running back Marion Barber.  Folk converted a 44-yard field goal early in the fourth quarter, and on the next play from scrimmage, Bears quarterback Rex Grossman threw an interception to Cowboys cornerback Anthony Henry, who ran it back for the score. The Cowboys proceeded to kill the clock, with Barber, who capped the scoring with a one-yard touchdown run.  Barber ended the night with over 100 yards rushing, and Cowboys wide receiver Terrell Owens caught eight passes for 145 yards.  The Cowboys improved to 3-0, while the Bears dropped to 1-2.
