Romo suffered a back injury Monday night when he was hit on a sack and took a pain-killing shot to return late in the game. In the buildup to the Cardinals clash, he didn't practice all week and was listed as questionable. NFL Media Insider Ian Rapoport reported that Romo planned to participate in Saturday's walkthrough.
Jerry Jones said this week the biggest impediment to Romo playing would be pain tolerance. Offensive coordinator Scott Linehan indicated that it is unusual for a quarterback to miss an entire week of practices and still play; however, there is not much usual about this situation with Jones' team.
If Romo can't play, the quarterback duties will fall to Brandon Weeden. The veteran backup played well in spot-duty Monday night. The veteran's extensive work with the first team during weekly practices (when Romo rested) and during OTAs should put him in a position to run the offense.
