Texas Felix Jones and Tashard Choice are prepared to move up the depth chart, if necessary, for Monday night's home game against the Panthers.
An MRI on Monday confirmed that Marion Barber has a quadriceps strain that could sideline him after an impressive start to the season. He suffered the setback late in the fourth quarter Sunday night during a 35-yard run.
With three tailbacks on the roster, Barber has been the workhorse, accounting for 32 of the team's 53 carries. After his 124-yard performance in the 33-31 loss to the New York Giants, Barber has 203 yards and two touchdowns.
Jones would replace Barber.
