The off-duty police officer who confronted Adrian Peterson used “vulgar language” and was “disrespectful” when asking the Vikings running back to leave the club in downtown Houston over the weekend, Peterson’s father, Nelson, told Jeremy Fowler of te St. Paul Pioneer Press.

“From what I’ve gathered, he was very disrespectful to Adrian,” Nelson said by phone Monday, July 9.

“Adrian is kind of frustrated because he’s the kind of guy who’s tried to do the right things in society and he cares about being a high-character guy,” Nelson said. “He has a 9-year-old daughter, so he doesn’t want her hearing in the news about how he’s being perceived.”

Jail evokes bad memories for the Peterson family. When Peterson was 13, Nelson was sentenced to 10 years in prison for laundering drug money.

“At the time, I didn’t realize the impact my actions can have on my kids,” Nelson said. “He knows that his actions affect him and his kids also.”

Peterson is still in Houston, according to Nelson, rehabbing a torn left anterior cruciate ligament, an injury he sustained Dec. 24, 2011, against Washington.
