Marion Barber (calf) is listed as doubtful for Week 17. Kahlil Bell and undrafted rookie Armando Allen will handle backfield duties against Minnesota. Barber will finish the season with 422 rushing yards on 114 carries (3.70 YPC). While he flashed an improved burst at times this year, it's clear Barber has lost the majority of his explosiveness and passing-game value. He'll be an offseason release candidate in Chicago.
