Henderson concluded that Peterson "has not demonstrated that the process and procedures surrounding his discipline were not fair and consistent."
Peterson said in an hour-long phone interview that he feels like the league is handling the situation absolutely wrong. In the interview he went on to compare his case to the Ray Rice situation, questioning why Rice was reinstated before he was. He also questioned the league's decision to appoint Henderson to his case, when he wasn't appointed to Rice's.
As the decision stands, Peterson will not be officially reinstated until April 2015. The NFLPA states that the decision completely ignores the league's collective bargaining agreement. The association also mentioned the league's failure to adhere to due process, and confirmed the inconsistent treatment of players.
Peterson plans to appeal the decision in federal court, and also said he has considered retiring. He said before making a decision like that, he would have to talk to his team about it. As of now, the future of Peterson as a Viking, and even as an NFL running back, remains in doubt.
