Minnesota Vikings running back Adrian Peterson mourned the death of his young son Friday, while words of support poured in from all corners of the sports world.

Authorities said a 2-year-old boy died Friday of injuries suffered in an alleged child abuse case in South Dakota, and a person with knowledge of the situation told The Associated Press the boy was Peterson's son.

Lincoln County State's Attorney Tom Wollman confirmed the death of the child, who had been in critical condition in a hospital with severe head injuries since Wednesday. The boy died at 11:43 a.m. at Sanford USD Medical Center in Sioux Falls after being removed from life support, Wollman said.

Wollman said he'll review police and medical reports before making further decisions about criminal charges, possibly by early next week. Joseph Patterson, 27, was charged with aggravated assault and aggravated battery in the child's death. He had a court appearance Friday and was ordered held on $750,000 cash bond.

Peterson declined to talk about the case after practice Friday, and prosecutors and police in South Dakota declined to confirm the boy was his son. However, a person with knowledge of the situation confirmed the connection to the AP on condition of anonymity because Peterson had requested privacy.

Speaking to reporters about an hour after the time of death, Peterson said he was certain he'll play Sunday against Carolina.

He smiled politely and spoke softly while taking questions at his locker.

"I'll be ready to roll, focused," Peterson said. "I will be playing Sunday, without a doubt."

"Football is something I will always fall back on," Peterson said. "It gets me through tough times. Just being around the guys in here, that's what I need in my life, guys supporting me. ... Things that I go through, I've said a thousand times, it helps me play this game to a different level. I'm able to kind of release a lot of my stress through this sport, so that's what I plan on doing."
