Fishburne 'quitting CSI'

Laurence Fishburne is closing the file on his 'CSI: Crime Scene Investigation' career.

The actor will not be back in the US crime drama this autumn, according to a source, who spoke anonymously because network CBS has yet to announce Fishburne’s departure.

Fishburne joined the CSI cast as Dr Raymond Langston midway through the 2008-09 season. He stepped in to replace departing star William Petersen.

The source said CBS and the show’s producers are taking Fishburne’s departure in their stride, aware that his film career made a long TV tenure unlikely.

CSI returns for its 12th season this autumn and continues to rank among the 20 top-rated shows.

Fishburne’s credits include 'The Matrix' films, and he is also in the forthcoming 'Contagion' with Matt Damon.
