A 2-year-old son of Minnesota Vikings star running back Adrian Peterson died on Friday in a Sioux Falls, South Dakota, hospital, the victim of alleged abuse by a man dating the boy’s mother, police confirmed.

Peterson’s father Nelson confirmed Friday afternoon that the child is Adrian Peterson’s. Peterson met with the media Friday, hours before the boy passed away, and said at the time he still planned to play in Sunday’s game against Carolina, but declined to get into details about the case.
