Sarah Payne's murderer, Roy Whiting, should have been fighting for life after being stabbed several times in prison, it was said.
The child murderer was "bloodied" after being attacked Thursday by two murderers in his cell, according to reports.
Whiting, 59, was hit with makeshift blades at Wakefield Prison in West Yorkshire before security forces intervened, it was reported.
After the alleged attack, Whiting, jailed for life for the murder of Sarah, aged eight, in 2001, was reportedly taken to the hospital with several stab wounds.
Sources told the Sun that two prisoners broke into Whiting's cell before "the rain hit him".
A source told the newspaper, "He was soaked with blood."
According to the report, doctors initially feared that he would not survive.
But after the quick reaction of prison staff and NHS doctors, Whiting is now in a stable state in the prison's health care pavilion.
A spokesman for the prison service told Mirror Online: "A prisoner from HMP Wakefield was attacked Thursday night and was hospitalized.
"The prisoner is now back in the prison in a stable state and the incident is being investigated by the police."

Mirror Online has previously reported that Whiting was a prominent man and had been attacked several times.
In 2002, he was injured in the razor blade and in 2011 he was stabbed to the eye with a sharpened toilet brush.
He spends his sentence listening to rock music and making models from matches.
The former mechanic is serving a 40-year sentence for the murder of West Sussex in 2000.
