The NFL Players Association's grievance with the league to get Adrian Peterson reinstated to the Vikings' roster has resulted in a hearing set for Monday, according to reports.

Pro Football Talk, citing sources, and Jay Glazer of Fox Sports both are reporting the hearing will be Monday.

An NFL spokesman, however, said "There has been no confirmation of a date for the NFLPA's grievance hearing."

When there is a hearing, it will be before arbitrator Shyam Das, Pro Football Talk reported. Das would have five days to issue a decision, meaning it could come before the Vikings' Nov. 23 game at TCF Bank Stadium against Green Bay.

The Vikings play at Chicago on Sunday before a three-game homestand.

If Peterson is reinstated, he likely would be eligible to play while the NFL conducts an investigation of its own. Peterson remains on the commissioner's exempt list, with full pay, following the settlement of his court case last week in Texas. Peterson reached a plea deal, pleading "no contest" to an injury-to-a-child misdemeanor.

The NFLPA, on Monday, filed an expedited, non-injury grievance to seek reinstatement of the Vikings running back, who missed eight games after he was charged on Sept. 12.

The NFLPA said in the statement the move was made "based on the explicit language in a signed agreement dated September 18, 2014. We asked the NFL to honor the terms of that agreement last week and as of now, they have failed to respond or comply."

Peterson, who pleaded no contest on Nov. 4 to a misdemeanor charge of injuring his 4-year-old son with a switch, can't return to the Vikings until the NFL reviews the case. The Vikings have deferred to the league in the matter, noting in a statement Monday that "at this time his potential reinstatement is under NFL guidelines."

Under terms of the collective bargaining agreement, an expedited grievance must be heard within seven days, and a ruling must be issued within five days following the hearing.

The NFL responded Monday night with a statement of its own.

"We have received the NFLPA's grievance on behalf of Adrian Peterson,'' the NFL statement read. "We have honored our commitment to Mr. Peterson and the NFLPA not to process or impose any discipline until the criminal charges pending in Texas were resolved.

"When Mr. Peterson decided not to contest criminal charges, we promptly advised both him and the NFLPA that we were prepared to consider what, if any, discipline should now be imposed under the Personal Conduct Policy. We asked Mr. Peterson and his representatives, including the NFLPA, for relevant information. We have not received any of the requested information, but remain prepared to schedule a hearing and make a determination as quickly as possible based on as much information as available.''

The Vikings initially deactivated Peterson against the Patriots during Week 2 just before he flew to Houston and was booked in Montgomery County. They reinstated Peterson the following week, only to place him on the exempt list after public backlash.

"When those decisions are made [by the NFL], we can make decisions," Vikings coach Mike Zimmer said at Monday's access. "Until then, really our hands are tied. There's nothing we can do about it other than what I've said all along. We love the kid. He's done everything I've asked him to do. And we support him. We want him to get through this for him, for him. Then we'll worry about all the other things we have to deal with at the time."
