With more than half of the fourth quarter still remaining, Chicago's defense already has been on the field for 30:09 of this game against New Orleans. The Bears stiffened near the goal line to preserve what is now a four-point lead, but it will be interesting to see if they can hold their own the rest of the way.
The Saints have found their running game and are starting to push back the Bears' defensive line. Chicago could potentially seal the game here with a long drive of its own followed by a score, but if not, the Bears' defense might be too worn down to hold the lead.
We'll be back with you shortly after the final gun.
