1. Adrian Peterson
Injury: Torn ACL & MCL
Accolades After Injury: 1x Pro Bowler, 2012 NFL Rushing Leader
A torn ACL and MCL would easily spell the end of anyone's career, especially a heavy-duty running back. Then again, not everyone is Adrian Peterson. Peterson brushed aside his devastating knee injury he suffered in December 2011 to make it back just 10 months later for the 2012 season. AP would go on to lead the league in rushing with 2,097 yards, and come within nine yards of breaking Eric Dickerson's 28-yr old single season all-time rushing record. He also received his fifth career Pro Bowl nod and carried the Vikings to the playoffs. Don't call it a comeback, he's been here for years.
