He is set to go free in October after being convicted of a 2007 confrontation at a Las Vegas hotel.
The former Hall of Fame running back was found guilty in 2008 – exactly 13 years to the day after he was famously acquitted for the killings of his ex-wife Nicole Brown Simpson and her friend Ron Goldman.
He and a group of five others stormed into a hotel room to confront two sports-memorabilia collectors to seize items that he claimed belonged to him from his own career.
The hearing for Prisoner 1027820 took place at the Lovelock Correctional Facility, a medium security prison in the Nevada desert.
