O.J. Simpson said that recently-jailed comedian Bill Cosby will need to be placed in protective custody because convicted sex offenders don’t fare well in prison.

Simpson, 71, told TMZ that the “nature of the crime” Cosby committed—sex assault—would make him a target for violence. Cosby, 81, was sentenced Tuesday to three to 10 years in prison for drugging and sexually assaulting Andrea Constand in 2004.

Cosby was convicted in April of three counts of aggravated indecent assault. His lawyers said they plan to appeal the conviction, according to CNN.

“I’m sure there will be guys protecting him but they’re gonna have to put him in protective custody…because it takes one nut, ya know?” he explained to the tabloid.

Simpson has a first-hand perspective on prison dynamics. The ex-footballer was released on parole in October 2017 after serving nine years in a Nevada prison for a 2007 armed robbery.

He told TMZ that Cosby is a liability behind bars and suggested that he serve his sentence at home.

“With his health and his age and the nature of the crime, there’s not a warden in this country wants the responsibility of a Bill Cosby,” Simpson said. “I think they should let him do his time under house arrest.”
