Just when you think Suge Knight's year-long stint in jail can't get any more catastrophic, TMZ reports that the former Death Row CEO has been relegated to solitary confinement.

Knight already lost his phone, mail and visitor privileges earlier this month. In legal documents obtained by TMZ, he claims that his forced isolation is a violation of his "basic human rights."

Knight ran over and killed a man in the parking lot of a Compton burger restaurant in January 2015. Since being arrested, he has made repeated appeals on behalf of his health -- he fainted upon hearing that his bail would be set at $25 million and has been confronted with a near-fatal blood clot and an (alleged) brain tumor. Solitary confinement will surely not improve his health... we'll keep you posted on further developments.
