Arbitrator Shyam Das will hear Minnesota Vikings star Adrian Peterson's grievance against the NFL early next week, a person with knowledge of the situation told USA TODAY Sports.

The hearing likely will take place Monday but could be pushed to Tuesday at a location to be determined, said the person, who spoke on condition of anonymity because details were to remain private.

Spokesmen for the NFL and the NFL Players Association said there has been no confirmation on a date.

Das has been an arbitrator for the NFL since 2004 and ruled against New Orleans Saints players in a 2012 bounty grievance.

He also was a longtime arbitrator for Major League Baseball, perhaps best known for overturning Milwaukee Brewers outfielder Ryan Braun's suspension for a failed drug test in 2012 based on a collector's failure to follow protocol. Das was fired months later. Braun admitted PED use last year.

As expected, the NFLPA announced Monday it has filed an expedited grievance on behalf of Peterson, who remains on the exempt list while the league considers potential discipline after he pleaded no contest last week to a misdemeanor reckless assault charge.

Article 43 of the 2011 collective bargaining agreement stipulates a hearing on an expedited grievance will be heard by an arbitrator within seven days of the filing, with a ruling to be issued five days after that.

The union believes Peterson's agreement to go on the exempt list should have led to his immediate reinstatement upon the resolution of his legal case. But the league says Peterson's status will be unchanged while it gathers information and considers discipline.

Peterson already has missed eight games since his Sept. 12 indictment on a felony charge of injuring his 4-year-old son while whipping him with a tree branch. He'll now miss Sunday's game against the Chicago Bears. The Vikings' next game after that is Nov. 23 against the Green Bay Packers.
