A second case of child abuse has surfaced against Adrian Peterson.

Peterson reportedly administered a "whooping" to another four-year-old son by creating a head wound that left a scar over the boy's right eye.

In a chain of text messages with the boy’s mother, Peterson admits that the wound occurred as Peterson disciplined the boy for cussing at a sibling.

The abuse has not yet led to charges against Peterson.

The boy’s mother filed a report with Child Protective Services; the outcome of the investigation is unclear.
