The Vikings tailback still participated and should be good to go this weekend when the Vikings go on the road to face the St. Louis Rams.
Fantasy Analysis: Peterson has been a top fantasy option all year, on pace to shatter Eric Dickerson's single-season rushing record.
Peterson's injury, though new, is nothing for fantasy owners to fret about. No. 28 will be on the field and ready to roll versus the St. Louis Rams defense on Sunday. Peterson needs only 169 yards to break the record, which isn't out of reach this weekend. It could be a historic weekend for the Vikings tailback.
