The television show's second season was postponed recently when it emerged that its star Andy Whitfield has been diagnosed with non-Hodgkin lymphoma.
New York Magazine has now claimed that the show's network Starz is developing a six-episode prequel series.
The move would mean that the sets and creative team could still be used until production on the second season of Spartacus begins.
Meanwhile, Spartacus writer Maurissa Tancharoen recently denied claims that the second season will not be filmed.
"Season two of Spartacus has NOT been cancelled," she wrote on her Twitter page. "Don't know where that rumour came from."
