Hopefully the image of Peterson limping off Mall of America Field at the end of the first quarter and then being carted away from the sidelines of the Vikings' loss to the Oakland Raiders will be replaced by him suiting up in Week 12 against the Atlanta Falcons. X-rays were negative, and Peterson has been durable, playing through occasional nagging injuries and missing only three games over four seasons. In a season in which fantasy owners have seen first-round draft picks leave with season-ending injury (Jamaal Charles), generally disappoint (Michael Vick) and really disappoint (Chris Johnson), Peterson is yet another reminder that there are no guarantees, no matter what your draft position is or how well a player is performing.
To see Eric Karabell's thoughts on Kevin Smith, Chris Johnson and others, you must be an ESPN Insider.
