MANKATO (AP) - The attorney for Adrian Peterson says the Minnesota Vikings star running back is off probation early for injuring his 4-year-old son.

Rusty Hardin says Peterson finished one-third of his probation and its terms, which allowed him to apply for early termination. Peterson is done with probation nine months after he pleaded no contest to recklessly injuring his son by striking him with a wooden switch. Hardin says a judge in Texas agreed that Peterson fulfilled the requirements of his probation and signed the early termination order late last week.

Peterson's probation also included 80 hours of community service, a $4,000 fine and counseling. Peterson has rejoined the Vikings at training camp in Mankato after playing only the first game of the 2014 season.
