Peterson hearing held Monday

While the NFL continues to deliberate on disciplinary action against Minnesota Vikings running back Adrian Peterson for a personal conduct violation, the grievance dispute over whether Peterson should be reinstated immediately was conducted Monday as scheduled via conference call with arbitrator Shyam Das and lasted "no more than 30 minutes," according to sources.

Das told representatives on both sides that he would have a decision "quickly," per one source. He must decide by Friday under the collective bargaining agreement article governing an expedited grievance, but sources said they sensed Das' decision could come as early as Tuesday.

Das will determine whether the letter that placed Peterson on the commissioner's exempt list with full pay required reinstatement as soon as his child abuse case was adjudicated. The NFL says its agreement included legal resolution and a review of the case that could result in disciplinary action.

Through the NFL Players Association, Peterson also requested again Sunday to meet personally with NFL commissioner Roger Goodell, according to a union source. That request has been ignored, the source said.

A league spokesman said the NFL did respond to Peterson's request Monday and pointed out that "we had offered exactly the type of meeting they had asked for and they elected not to participate, leaving us to move forward based on the info available."

The league had invited Peterson and the union to meet with a variety of league officers Friday for a disciplinary hearing, sources said, but the union believed the normal protocols for disciplinary hearings were being dramatically revised without any agreement to the process.

The NFLPA persists in its view that the meeting the league proposed last week was an effort to impose a new process that would include "outside league participants." The NFL has wanted to involve various experts on domestic violence and child abuse that it now has either hired or retained as consultants. The union says any change from the previous standard practice should be collectively bargained, which the NFL has declined. The league notes that the personal conduct discipline process remained at the commissioner's discretion in the 2011 labor agreement.
