Cowboys owner-general manager Jerry Jones, studying the Senior Bowl workouts, admitted Marion Barber's string of injuries the last two years could cause a change in how the offense divides carries among the running backs.
injuries have limited Barber's production down the stretch in each of the last two seasons. In 2008, a lame Barber gained only 15 yards on 13 carries in the final four games. In two playoff games this season, Barber became only the second back in this century to have more than 12 carries and fewer than 20 yards rushing. He ran 11 times for 18 yards.
``We have had an injury issue there at the end of each of the last two seasons,'' Jones said. ``That may have something to do with the amount of time we can give the other backs. That could impact that decision.''
