The NFL Players Association sent a letter to the NFL on Friday, calling for the immediate reinstatement of Adrian Peterson per the agreement the sides made for the Minnesota Vikings running back to go on the commissioner's exempt list in September, according to sources. The agreement to place Peterson on the commissioner's exempt list explicitly states that Peterson would be removed from the list upon resolution of his legal matter, sources said. Peterson pleaded no contest to a misdemeanor last week.

If the NFL declines to comply with the agreement, the NFLPA can then file an expedited non-injury grievance to have Peterson reinstated immediately.
