U.S. actor Gary Dourdan is set to leave the long-running television crime drama "CSI," a source told EW.com.

Dourdan's departure follows that of former co-star Jorja Fox, who left the 8-year-old series late last year.

The insider told EW.com the decision regarding Dourdan was a mutual one made by the actor and CBS/Paramount, the studio that produces the show for CBS.

The source said it is possible Dourdan will make occasional guest appearances after he leaves.

"CSI" star William Petersen recently signed on for one more season, but he will only appear in a limited number of episodes so he can pursue other projects, EW.com said.
