The NFL has announced that Minnesota Vikings running back Adrian Peterson could face discipline from the league after he pleaded no contest to one count of misdemeanor reckless assault last week.

Peterson was indicted for a charge of reckless or negligent injury to a child, in relation to an incident where he used a small tree branch to discipline his son earlier this year.

The 29-year-old will be on probation and will also pay a $4,000 (£2,500) fine, as well as serving 80 hours of community service. However, the NFL has warned Peterson that he could also face punishment from the league.

The NFL said in a statement: "The NFL advised Adrian Peterson this afternoon that following his plea agreement to resolve his criminal case in Texas his matter will now be reviewed for potential discipline under the NFL's personal conduct policy.

"As part of the process, the NFL has requested that Peterson submit relevant information regarding his case and meet with designated experts who will make recommendations for the commissioner's consideration.

"Peterson also will have the opportunity to have a hearing prior to the issuance of any discipline. Pending completion of the process, Peterson's status on the Reserve/Commissioner Exempt list will remain unchanged."

The Vikings said in a statement: "In regards to Adrian Peterson's status with the Minnesota Vikings, at this time his potential reinstatement is under NFL guidelines.

"As an organisation, we respect and understand the league's process. In the interim, our focus is on the team and preparing for this weekend's game against the Bears."

Peterson has not played for the Vikings since being deactivated in week two of the season following the outbreak of the news.
