Larry Nassar, the disgraced sports doctor convicted of sexually abusing members of the U.S. Olympic women’s gymnastics team, has reportedly been stabbed in prison.

Nassar was stabbed multiple times during an altercation with a fellow prisoner at a federal penitentiary in Florida.

The 59-year-old Nassar is serving a 175-year sentence for abusing more than 150 young girls over a period of nearly two decades.  He was convicted in 2018.
