Now that Adrian Peterson has settled the child-abuse charges against him, he wants back in the NFL and is prepared to sue the league if it continues to keep him off the field, according to sources who spoke with Yahoo Sports.

According to the website, "The NFL Players Association filed a grievance against the NFL on Monday, asking the league to remove Peterson from the commissioner's exempt list." The NFLPA cites "explicit language" that Peterson could be reinstated once his legal case was resolved.

Peterson's initial charges of child abuse were reduced to a misdemeanor after the Vikings running back pleaded no contest to reportedly beating his 4-year-old son with a "switch." Since he reached an agreement with the court, the NFL has reportedly not moved to reinstate Peterson, who could technically be reinstated by the league and then suspended for the remainder of the season, according to sources who spoke with Yahoo Sports.

If the NFL were to suspend Peterson, it is expected that the NFLPA would immediately appeal the suspension. Although the NFLPA would not support Peterson's suspension, it also doesn't approve of his being in indefinite purgatory, and many believe that the threat of a lawsuit may push the NFL to action.

According to the website, Vikings executives may be holding up Peterson's reinstatement because the front office is split on whether it wants Peterson to return.Ā
