Adrian Peterson knows what Jordy Nelson is going through (The Associated Press)

Vikings running back Adrian Peterson knows what Green Bay receiver Jordy Nelson is going through. The Packers star has returned from a right ACL injury that forced Nelson to miss the 2015 season. Peterson tore his left ACL late in the 2011 season, then came back the following year to rush for nearly 2,100 yards in an NFL MVP campaign.
