Adrian Peterson has been accused of child abuse for the second time in less than a week.
According to a new report by KHOU, the Minnesota Vikings running back sent a different four-year old son back to his mother last June with a scar on his forehead.
The station says Peterson sent the mother a text message that claimed the toddler smacked his head on a car seat... but when the boy's mother pressed the issue, Peterson admitted to striking hitting the child.
This story is developing.
UPDATE: Sources tell TMZ that the the child accidentally hit his head on a car seat while being punished by Peterson, but Peterson did not directly hit the boy.
