Adrian Peterson’s two year old son is in critical condition in a Sioux Falls, S.D. hospital, the victim of alleged abuse.

This was confirmed on Friday by Nelson Peterson (Adrian’s father).

Peterson met with the media Friday and said he still planned to play in Sunday’s game against Carolina, but declined to get into details about the case.

Peterson missed practice on Thurs. but stated in a press conference Friday.  “I really appreciate all the support that I’ve been receiving from fans, the Vikings organization,” said Peterson. “This is a private matter and I would ask you all to please just respect my privacy and not ask at all about the situation at hand.

Peterson went on to say. “I plan on playing Sunday,” he said. “I will be playing Sunday, correct that. I’ll be ready to roll, focused. I’m worried about getting a W on Sunday, being 1-0… You know, football is something I will always fall back on. It gets me through tough times. Just being around the guys in here, that’s what I need in my life, guys supporting me and just being able to go out and play this game I love. Things that I go through, I’ve said a thousand times, it helps me play this game to a different level.

In a separate report, Sioux Falls police spokesman Sam Clemens told USA TODAY Sports that the child remains hospitalized in critical condition. Tom Wollman, the prosecutor in Lincoln County, S.D., said the child is “unresponsive.”

The suspect of the alleged abuse is Joseph Robert Patterson, 27, who has been charged with aggravated assault and aggravated assault on an infant.

Patterson, who has a prior arrest with another woman on domestic abuse is being held with a bond set at $750,000 in cash.

“The injuries they found were head injuries,” Clemens said. “It was obvious to medical staff that abuse had taken place and that those injuries weren’t accidental.

Vikings coach Leslie Frazier said Friday that it would be up to Peterson whether he plays this week.

“We’ll see how things go with him,” Frazier said. “We expect him to play, but this is a very personal situation that he’s dealing with.”
