Simpson put nine years of prison behind him today, walking out of Nevada's Lovelock Correctional Center after completing a stint for his role in a 2007 Las Vegas robbery.
State prisons spokeswoman Brooke Keast said Simpson's release was timed to avoid media attention.
Legal analysts say that none of Simpson's pension income can be taken away to pay off the hefty multi-million dollar civil ruling against him.
Simpson is free after he was officially released from prison in the early hours of October 1, after spending nearly nine years imprisoned for an armed robbery in Las Vegas.
Tom Scotto, a friend of Simpson's, said the former National Football League star will not hide once he's released from prison.

The police say investigators plan to meet with prosecutors to determine whether charges will be brought. The address is not now registered with the state as a licensed Family Child Care Home.
Keast said Simpson was "upbeat, personable and seemed happy to get on with his life". A scripted series about the actual trial, The People v. O. J. Simpson: American Crime Story, also racked up nominations and awards, including a Golden Globe and a Primetime Emmy. Simpson could be on parole until September 29, 2022.
The midnight timing was "to ensure public safety and reduce the potential for incident", the department said in a brief statement that accompanied the video and a photo showing Simpson signing some papers. "Maybe not the first day or second, but he is going to go out".
Simpson has personally expressed an interest in going back to Florida, and Scotto said he expects his friend will move back there and buy a home, if his parole allows it. He was ordered to serve a minimum of nine years before he was eligible for parole.
But Florida prison officials said documents weren't filed, and the state attorney general says she doesn't want Simpson to live in the state.
The 70-year-old Simpson told the parole board that he wanted to live in Florida. The former Buffalo Bills player will have to adhere to the conditions set by the Nevada parole board, which include banning him from consuming alcohol in large quantities or hanging out with ex-convicts or people who engage in criminal activity.
