Peterson is dealing with a shoulder injury, but he practiced in full all week. Peterson has dealt with more serious injuries than this one, so he should be fine to play on Sunday.
Fantasy Impact: Adrian Peterson has gotten healthier as the season has gone on, and as a result, he has returned to the top of the fantasy football running back rankings. He is having another outstanding season and continues to amaze people.
Consider him an every week starter. His matchup against a banged up Packers defense this week shouldn't scare you.
