A hearing to determine whether Adrian Peterson is allowed to suit up for the Vikings is likely to take place Monday.

An NFL spokesman said Tuesday that there is no confirmed date for the hearing, but two published reports said it would be Monday.

The NFL Players Association filed an expedited non-injury grievance Monday to seek reinstatement of Peterson, who has been on the commissioner's exempt list since Sept. 18. According to the collective bargaining agreement, the hearing must take place within seven days of the grievance being filed.

Peterson was sidelined pending settlement of his court case in Texas on charges of injuring one of his children. He agreed to a plea deal Nov. 4, pleading no contest to a misdemeanor charge of injury to a child.

The union maintains Peterson should instantly be reinstated. The NFL said it hoped to receive more information on Peterson's case before determining discipline under the league's personal conduct policy, then removing him from the list.

Peterson has missed eight games but is drawing his full salary.

The grievance will be heard by veteran sport arbitrator Shyam Das, Pro Football Talk reported. Das was arbitrator for Major League Baseball labor disputes from 1999-2012. Das has five days to issue his decision, meaning it could come on Nov. 22 — the day before the Vikings' Nov. 23 game against Green Bay at TCF Bank Stadium.

If Peterson is reinstated, he likely would be eligible to play while the NFL concludes its investigation. A league spokesman said Monday that the NFL had requested relevant information from Peterson but had not received any response.
