Potential discipline for Minnesota Vikings running back Adrian Peterson under the NFL personal conduct policy has become more complicated and contentious.

The league says Peterson declined to meet Friday about his case so it proceeded with a review without him. The league also says it was unwilling to postpone the hearing beyond this week, citing the NFL Players Association's desire to resolve the situation promptly.

Peterson has been on paid leave for two months. He pleaded no contest to misdemeanor reckless assault in Texas for hitting his 4-year-old son with a wooden switch.

The NFLPA filed an expedited grievance against the NFL to return Peterson to the roster until punishment is determined. That issue will be moderated Monday by an arbitrator.
