Adrian Peterson smiles in mugshot after turning himself in

Adrian Peterson was all smiles as he took his mugshot after turning himself into Montgomery County, Texas, authorities early Saturday morning.

Peterson turned himself in after an arrest warrant was put out for him because he was indicted on charges of reckless or negligent injury to his child.

Peterson posted his $15,000 bond and left early Saturday.

The star running back was deactivated for Sunday’s game by the Minnesota Vikings after news of his indictment emerged Friday. Peterson reportedly admitted to beating his 4-year-old son with a switch, but said he didn’t did not think there was anything wrong with his form of discipline and that he did not intend to hurt the boy. The 4-year-old boy reportedly told police Peterson hit him in the face and that he was worried about being hit in the face if he told on his father.

A grand jury reviewing all the facts in the matter decided Peterson’s discipline fell beyond what would be considered reasonable.
