Adrian Peterson will replace Anthony Thomas as the starting running back. Peterson, who played well at the end of last season when Thomas was out with a fractured finger, has just one carry for three yards in the past four games and only six carries for 15 yards this season.
Rabih Abdullah, who missed last week's game with a concussion after rolling his SUV and being arrested and charged with DUI, leaving the scene of an accident and improper lane usage, should see more action backing up Peterson. Abdullah, who plays mostly on third downs, has four carries for six yards this season and four receptions for 24 yards.
Thomas is averaging 5.5 yards per carry. He was hurt during the Saints game but played through it and rushed for 96 yards on 21 carries. Only afterward did Thomas experience swelling and enough soreness to eliminate him from Sunday's game.
BY THE NUMBERS: RB Anthony Thomas and QB Kordell Stewart have 608 of the Bears' 656 rushing yards this season, and neither is expected to play on Sunday.
