Minnesota Vikings running back Adrian Peterson says he is prepared to fight, even sue the NFL if it becomes necessary if the league continues to hold his career in limbo, according to sources.

From Yahoo News:

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 cited an agreement between Peterson and the NFL, which “based on explicit language” would reinstate the running back once his legal case was resolved.

Last week, Peterson pleaded no contest to a misdemeanor charge related to disciplining his 4-year-old son with a wooden switch. Since that plea deal, the NFL has not moved to reinstate Peterson, and has not given a timetable for when it would resolve the issue. If the league reinstates Peterson and then subsequently suspends him, it is expected that the NFLPA will appeal the suspension.

The Vikings’ front office has expressed support for Peterson’s return, according to two sources familiar with the team and Yahoo Sports.

However, at least one Viking’s executive expressed concern for how his return would impact the team’s sponsorship deals.

Thoughts on a possible lawsuit?

Should Peterson be allowed to play?
