Second child abuse allegation against Vikings' Peterson comes to light

Minnesota Vikings running back Adrian Peterson was accused of abusing another of his children in an incident more than a year before the All-Pro was indicted on felony charges last week, a Houston television station reported Monday.  
KHOU-TV reported Monday that the incident occurred in June 2013, while the boy, then four years old, was visiting Peterson from out of state. The station reported that the child suffered a head wound that left a scar above his right eye. The scar was still visible weeks later. 
The station also obtained text messages between Peterson and the boy's mother in which Peterson said he had disciplined his son for cursing at a sibling. 
"I felt so bad," one of Peterson's messages says. "But he did it to his self [sic]." Peterson never answers when asked what he hit the child with, but later says "Be still n take ya whooping he would have saved the scare [scar]. He aight [all right]."
A law enforcement official confirmed to KHOU that authorities had known about the allegations, and the station reported that the mother had filed a report with Child Protective Services. TMZ reported that the CPS investigation determined that the child had sustained the head injury accidentally while Peterson was punishing him and no charges were filed. Texas law permits parents to administer "reasonable punishment" to children.
The latest allegation surfaced hours after Peterson was reinstated to the Vikings' active roster after being deactivated from the team's 30-7 loss to the New England Patriots Sunday. The team released a statement to NBC Sports' ProFootballTalk.com late Monday confirming that they had known about the 2013 allegation when the decision to reinstate Peterson was made. 
Peterson's attorney Rusty Hardin responded to the allegation by saying "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."
On Monday, the Radisson hotel chain said it was suspending its sponsorship of the Vikings, citing its "long-standing commitment to the protection of children." Radisson's sponsorship includes a press banner that is behind those speaking at Vikings news conferences. On Monday, the banner was behind Vikings general manager Rick Spielman as he discussed the team's decision to reinstate Peterson.
Peterson is scheduled to appear in court in Montgomery County, Texas Oct. 8. He faces charges of reckless or negligent injury to a child. Peterson is accused of using a wooden switch on another of his sons this past May, leaving deep bruises that were visible several days later.
