Vikings RB Adrian Peterson (ankle, questionable) took limited practice reps again Friday and is questionable for Week 14. Peterson says he's "80 percent" and clearly wants to play. But there is little reason for him risk re-injury for a 2-10 team. If he does play, he'll be a high-risk, high-reward play against a Lions defense that is without Ndamukong Suh.
