Adrian Peterson may not play in the preseason July 28, 2014 by Paul Jackiewicz Leave a Comment Vikings head coach Mike Zimmer told Ian Rapoport of the NFL Network that running back Adrian Peterson may not play in the preseason. Mike Zimmer told me he has nothing to see from Adrian Peterson in preseason. If he wants to get a carry or 2, he will. But may just get none — Ian Rapoport (@RapSheet) July 28, 2014 This is a smart move by Zimmer. Peterson has nothing to prove.
