Vikings star running back Adrian Peterson is off probation nine months after he pleaded no contest in Texas to recklessly injuring his 4-year-old son, substantially shortening the original two-year probation order.

Peterson's attorney, Rusty Hardin, said Wednesday night that the Vikings' MVP finished one-third of his probation and its terms, allowing him to apply for early termination. The judge agreed that he fulfilled the provisions of the probation and signed the early termination order late last week, Hardin said.

The terms included 80 hours of community service. Peterson also was ordered to pay a $4,000 fine after his plea to the misdemeanor.

Montgomery County (Texas) District Attorney Brett Ligon told Houston television station KHOU that he plans to ask the judge to reconsider his decision. Ligon told KHOU that Peterson didn't fulfill a requirement to do a public service announcement concerning child discipline. He also told the station that Peterson may have failed to complete other terms of his probation.

Asked about those comments Friday, Hardin said, "Well, I don't want to get in a fight with him about it."

He said the probation department notified Peterson that he completed the requirements, and Hardin applied for early termination, giving the district attorney's office 48 hours' notice, he said.

"They had an opportunity to object. They did not, and the judge granted it. … And now apparently they're upset," he said. "And it's their right. But it's over and done with. And now Adrian is going to go play football."

Ligon couldn't be reached Wednesday night.

Peterson played only the first game in the 2014 season. He rejoined the Vikings in June and is working out at the team's training camp in Mankato.

In June, Peterson told reporters that he had fulfilled all the sentencing requirements.

But Montgomery County Assistant District Attorney Phil Grant said at that time that he didn't believe that Peterson had completed his required public service announcements. Peterson's sentence also included counseling and parenting lessons.
