Adrian Peterson's appeal of his suspension has been denied.

NFL spokesman Greg Aiello announced on Friday afternoon that Harold Henderson has denied Peterson’s appeal of the suspension without pay through at least the end of the 2014 season that was handed down by the league in November. Henderson, a former league official, was appointed to hear the appeal by Commissioner Roger Goodell.

“I conclude that the player has not demonstrated that the process and procedures surrounding his discipline were not fair and consistent,” Henderson said in a statement released by Aiello. “He was afforded all the protections and rights to which he is entitled, and I find no basis to vacate or reduce the discipline.”

Peterson will be eligible for reinstatement on April 15.
