Minnesota Vikings running back Adrian Peterson did not appear at a scheduled disciplinary hearing with the NFL on Friday after agreeing to attend last week, according to ESPN.

The NFL claimed that Peterson refused to give the league an alternative date for the disciplinary hearing, which stems from his arrest for child abuse.

Friday’s meeting was more significant than the conference call scheduled for 2 p.m. ET on Monday. The NFL Players Association filed an expedited, non-injury grievance on behalf of Peterson, requesting removal from the Commissioner’s Exempt list.

The Friday meeting was originally scheduled last Tuesday, but the NFLPA told the league on Thursday that it was not available, according to the report.

“We informed the union that we were unwilling to postpone the hearing beyond this week given that the player and union had both expressed a strong desire to resolve this matter as soon as possible, and we had been given no meaningful reason why Adrian and the union could not appear and participate,” a league official told ESPN. “We offered other alternatives for this week, but those also were not acceptable. We also have yet to receive more than cursory materials in response to our requests for information on the case. Accordingly, we went forward with the review on Friday as scheduled.

“We had hoped that Adrian would take advantage of his opportunity to be heard and present whatever information he believes should be considered before a decision on discipline, counseling and services is made. Because he and the NFLPA elected not to do so, we will have to address this based on the information currently available to us.”

NFLPA spokesperson George Atallah said Peterson’s attorney, Rusty Hardin, provided the league with a letter claiming that it is against Texas state law to give the NFL the requested documents. The incident that led to Peterson’s arrest occurred in Texas.

The union also said it made Peterson’s clinician available to the league.

“The League office seems more focused on creating an arbitrary disciplinary process for Adrian instead of honoring a signed agreement to remove him from the Commissioner’s list,” Atallah wrote in an e-mail to ESPN. “They are simply making stuff up as they go along. They should commit their efforts to meeting us at the table to collectively bargain a new personal conduct policy.”

Peterson has not played for the Vikings since Week 1 but is being paid his full salary — $11.25 million for the 2014 season — while away from the team.

On Nov. 4 in Montgomery County, Texas, Peterson pleaded no contest to a misdemeanor assault charge, was placed on probation and ordered to pay a $4,000 fine. The charge was reduced from felony child abuse for an incident in which Peterson admittedly used a tree branch to whip his 4-year-old son.
