Adrian Peterson was investigated in another incident where he allegedly injured one of his children in a discipline incident, according to Houston television station KHOU.

Peterson's lawyer, Rusty Hardin, issued a statement after the station aired its story on its 6 p.m. news.

Said Hardin: "The allegation of another investigation into Adrian Peterson is simply not true. The allegation is more than one year old and authorities took no action. An adult witness admittedly insists Adrian did nothing inappropriate with his son."

Peterson, who was reinstated by the Vikings on Monday after sitting out Sunday's game because of a criminal charge against him, was not charged in the incident reported by KHOU.

The children in the two incidents have different mothers, the station reported.

The station had alleged text messages between Peterson and the mother of the child in the incident in June of 2013 in Texas where Peterson admitted he hit the child while the child was in a car seat.

Two pictures were texted between Peterson and the mother. One showed the child with bandages on his forehead, and the other showed a scar allegedly left by the cuts.

The child's mother filed a report with Child Protective Services but the result of that was not known, the station added.

The Vikings issued this statement: "As part of the information we have gathered throughout this process, we were made aware of an allegation from 2013 in which authorities took no action against Adrian. We will defer any further questions to Adrian's attorney Rusty Hardin."
