UPDATE: The Vikings have released a statement regarding this most recent allegation. It is as follows:
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.
Earlier, we brought you a story of a second possible abuse allegation against Adrian Peterson, and Peterson's attorney has replied quickly and forcefully.
The allegation of another investigation into Adrian Peterson is simply not true," Rusty Hardin, Peterson's lawyer, said in a statement. "This is not a new allegation, it's one that is unsubstantiated and was shopped around to authorities in two states over a year ago and nothing came of it. An adult witness adamantly insists Adrian did nothing inappropriate with his son. There is no ongoing or new investigation.
This is a substantial departure from Hardin's statement regarding the initial allegation and indictment from Friday, where Hardin explained that Peterson was disciplining his son, and didn't think he was doing anything wrong. Essentially, he admitted to what happened while trying to give a reasonable explanation for extenuating circumstances. Peterson was deactivated for Sunday's game against New England, and was reinstated earlier today by the Minnesota Vikings.
This second allegation came out a few hours after the press conference announcing Peterson's reinstatement, and Hardin's statement is forceful and straight to the point in discrediting this most recent incident first reported by KHOU TV.
