Adrian Peterson denied that he backed out of a scheduled disciplinary hearing with the NFL on Friday, saying the league is trying to "impose a new process of discipline on me" and circumvent the collective bargaining agreement.

"The report that I backed out of a meeting with the NFL is just not true. When Roger Goodell's office asked that I attend the 'hearing' on Friday, I consulted with my union and learned that this 'hearing' was something new and inconsistent with the CBA," he said in a statement released Sunday morning.

Peterson claims that the NFL was late to respond to questions about the nature of Friday's hearing in connection to his child-abuse case in Texas despite the NFL Players Association's repeated attempts to gain clarity from the league.

"On Tuesday, Wednesday, and Thursday of this past week, my union sent emails, letters, and had conversations with [Goodell's] office on my behalf asking about the nature of the hearing, how it was to occur, who would participate, and its purpose," Peterson said. "We repeatedly asked them to respond quickly to my questions because I want to cooperate and get back on the field, but they didn't respond until late Wednesday evening, and even then they didn't answer important questions about their proposed 'hearing.'

"After consulting with the union, I told the NFL that I will attend the standard meeting with the commissioner prior to possible imposition of discipline, as has been the long-term practice under the CBA, but I wouldn't participate in a newly created and non-collectively bargained pre-discipline 'hearing' that would include outside people I don't know and who would have roles in the process that the NFL wouldn't disclose."

Peterson says the NFL is acting unfair in his case.
