Earlier this week, Vikings running back Adrian Peterson secured an important off-field victory, persuading a grand jury to not recommend formal charges of resisting arrest, stemming from a July incident in Houston.

Under the league’s personal conduct policy, the incident technically will trigger a review. A source with knowledge of the situation explains that discipline is unlikely, based on the accounts and reports regarding the exoneration of Peterson.

The official language of the personal conduct policy provides Commissioner Roger Goodell with a wide range of discretion. In the past, discipline has been imposed even in the absence of an arrest.

In Peterson’s case, this first incident most likely won’t result in punishment. It could, however, make the Commissioner more inclined to take a careful look at Peterson if there ever is a second incident.
