A bulging disc or herniated disc (also known as a ruptured disc) is the result of pressure upon a intervertebral disc that results in a protrusion from the disc. A bulging or herniated disc can be the result of injury, wear and tear upon the spine from natural aging, or degenerative disc disease.
Simpson was sentenced to nine to 33 years in Nevada state prison but was granted parole on some convictions in July, meaning he must serve at least four more years locked up.
Simpson is currently in prison due to a 2007 arrest. As reported by the Washington Post, Simpson was arrested in September 2007 on multiple felony charges in the armed robbery of a Las Vegas hotel room involving sports memorabilia allegedly stolen from Simpson's own collection.
