Vikings coach Leslie Frazier had hinted on Friday that Peterson, the leading rusher in franchise history, might play against Detroit.
Peterson will finish the season with 1,266 rushing yards and 10 touchdowns on 279 carries. It marks the second-lowest yardage total of Peterson's career, behind only his injury-plagued 2011 campaign.
