The last time Adrian Peterson visited FedEx Field in Landover, Md., he writhed on the turf, as other players knelt and prayed. He rode the medical cart off the field, knowing there was a "99.9" percent chance he had torn ligaments in his left knee.
He sat in the locker room, hearing cheers as distant echoes, already anticipating months of tedious recovery.
On Dec. 24, 2011, at the lowest point of his professional career, Adrian Peterson called over Jeff Anderson, the Vikings director of corporate communications.
Peterson had noticed a kid wearing his jersey behind the bench. The kid, Keenan Wynn, had hung a banner listing Peterson's autograph as one of his Christmas wishes.
"Mr. Anderson came out in the fourth quarter and said, 'Excuse me, do you mind if I borrow that jersey for a moment?'" said Dr. Michael Wright, who mentors Wynn.
Peterson autographed the jersey, wishing Wynn, "Merry Christmas."
"I started to tear up," Wright said. "I know a lot of the athletes, and that moment made me feel like a kid again. Never had a player of that caliber, at a time when he was injured and worried that he may never play again, think of doing something so generous."
Peterson keeps giving, in so many ways.
