The former US police officer convicted of murdering George Floyd in 2020 is “expected to survive” after he was injured in a knife attack in jail.
Prison officers performed "life saving measures" on Derek Chauvin, 47, before he was taken to hospital, where his condition is said to be stable.
The attack, at a medium-security prison in Tucson, Arizona, on Friday came a week after the US Supreme Court threw out Chauvin's appeal against his conviction.
He is serving a state sentence of 22 years for second-degree murder concurrently with a 21-year federal sentence for violating Floyd's civil rights.
Mr Floyd died on May 25, 2020, in Minneapolis, after Chauvin pressed a knee on his neck for nine-and-a-half minutes. Three other officers at the scene received lesser sentences.
The killing prompted widespread protests against police brutality and racism in the US.
Brian Evans, a spokesman for the Minnesota attorney general's office, said on Saturday that they had "heard that he (Chauvin) is expected to survive".
Minnesota Attorney General Keith Ellison said he was "sad to hear" that Chauvin had been the "target of violence" inside prison.
"He was duly convicted of his crimes and, like any incarcerated individual, he should be able to serve his sentence without fear of retaliation or violence," he said in a statement.
The justices turned away Chauvin's appeal that he filed after an appellate court upheld his 2021 murder conviction and rejected his request for a new trial.
Chauvin had argued that jury bias and rulings by the judge deprived him of a fair trial.
