The attack happened at the Federal Correctional Institution, Tucson, a medium-security prison that has been plagued by security lapses and staffing shortages. The person was not authorised to publicly discuss details of the attack and spoke to the AP on the condition of anonymity.
The Bureau of Prisons confirmed that an incarcerated person was assaulted at FCI Tucson about 12.30pm on Friday. In a statement, the agency said responding employees contained the incident and performed "life-saving measures" before the inmate, who it did not name, was taken to a hospital for further treatment and evaluation.
No employees were injured and the FBI was notified, the Bureau of Prisons said. Visiting at the facility, which has about 380 inmates, has been suspended.
Messages seeking comment were left with Chauvin's lawyers and the FBI.
Chauvin, 47, was sent to FCI Tucson from a maximum-security Minnesota state prison in August 2022 to simultaneously serve a 21-year federal sentence for violating Floyd's civil rights and a 22 year and six months state sentence for second-degree murder.

Chauvin's lawyer, Eric Nelson, had advocated for keeping him out of general population and away from other inmates, anticipating he would be a target. In Minnesota, Chauvin was mainly kept in solitary confinement "largely for his own protection," Nelson wrote in court papers last year.
Last week, the US Supreme Court rejected Chauvin's appeal of his murder conviction. Separately, Chauvin is making a longshot bid to overturn his federal guilty plea, claiming new evidence shows he didn't cause Floyd's death.
Floyd, who was Black, died on May 25, 2020, after Chauvin, who is white, pressed a knee on his neck for nine minutes on the street outside a convenience store where Floyd was suspected of trying to pass a counterfeit $20 bill.
Bystander video captured Floyd's fading cries of "I can't breathe." His death touched off protests worldwide, some of which turned violent, and forced a national reckoning with police brutality and racism.
Three other former officers who were at the scene received lesser state and federal sentences for their roles in Floyd's death.
