Minnesota Vikings running back Adrian Peterson's suspension appeal ruling was overturned by judge David Doty today,  as he ruled in favor of the NFL Players Association in their lawsuit against the NFL on behalf of the Pro Bowl runner. It will now go back to the NFL for another ruling under the collective bargaining agreement. Peterson was suspended by NFL commissioner Roger Goodell through April 15 following the running back's child abuse case. "“This is a victory for the rule of law, due process and fairness," NFL Players Association executive director DeMaurice Smith said. "Our collective bargaining agreement has rules for implementation of the personal conduct policy and when those rules are violated, our union always stands up to protect our players' rights. This is yet another example why neutral arbitration is good for our players, good for the owners and good for our game.”" The Vikings may try to release him, restructure his contract or trade him, but have said they want to keep him on the roster. Peterson's agent, Ben Dogra, got in a heated exchange with Vikings vice president Rob Brzezinski last week at the NFL scouting combine. Doty typically rules in favor of the players' union. Doty agreed with the union's argument that Goodell acted outside his authority when he suspended Peterson. Peterson is scheduled to earn $12.75 million in 2015 and count $15.4 million against the salary cap. Follow me on Twitter: @RavensInsider Aaron Wilson covers the Ravens for The Baltimore Sun
