As Adrian Peterson remains in the limbo of the NFL’s Commissioner’s Exempt List, the players’ union says it’s time to let him resume his career.

The NFL Players Association released a statement Monday afternoon saying it has filed a grievance to get Peterson off the exempt list.

“The NFLPA has filed an expedited, non-injury grievance to remove Adrian Peterson from the Commissioner’s Exempt list based on explicit language in a signed agreement dated September 18, 2014,” the statement says. “We asked the NFL to honor the terms of that agreement last week and as of now, they have failed to respond or comply. It is our obligation to protect all players’ rights, and we will pursue any and all breaches of any contract between a player and his team or the NFL.”

Peterson, who has not played since the Vikings’ first game of the season, pleaded no contest last week to resolve a legal case that began when he was charged with injuring his 4-year-old son while beating him with a switch. The NFL has said it has no schedule for determining whether Peterson will be suspended or when he will be allowed to return to the field.
