Larry Nassar, the disgraced sports doctor who admitted to sexually abusing hundreds of athletes, was stabbed 10 times at a federal prison in Florida on Sunday.
Officials with the Bureau of Prisons confirmed that an inmate was assaulted around 2:35 p.m. Sunday at United States Penitentiary Coleman but declined to identify the people involved.
An unidentified source told The Associated Press that the inmate was Larry Nassar.
Joe Rojas, president of the union that represents employees at the prison, told NBC News another inmate stabbed Nassar twice in the neck, twice in the back, and six times in the chest, leaving him with a collapsed lung.
ABC News reports Larry Nassar was stable as of Monday morning.
Circumstances leading up to the stabbing were not released.
The United States Penitentiary Coleman is a high-security facility in Sumterville that houses just over 1,200 inmates.
In 2017, Nassar was sentenced to 60 years in federal prison and 175 years in Michigan state prison.
Larry Nassar pleaded guilty to additional criminal sexual conduct charges and got an addition prison sentence of up to 125 years.
