The NFL won an arbitration hearing regarding Minnesota Vikings running back Adrian Peterson as arbitrator Shyam Das ruled that the league can keep him on the commissioner's exempt list.

Since Peterson was suspended without pay for at least the rest of the season, this ruling basically ensures he won't be playing this season.

Peterson plans to file an appeal of his punishment, which stems from his no contest plea in a child abuse case where the NFL star admitted that he hit his four-year-old son with a wooden switch and inflicted injuries to his thighs, genitals, buttocks, hands and back.

Das ruled that Peterson "failed to establish on this record that the NFL violated either the letter agreement or the CBA."

Now, Peterson will stay on the exempt list while he appeals his suspension.
