The original cast member has signed a new pact with CBS Television Studios to return to the long-running procedural for its upcoming 13th season.

CSI: Crime Scene Investigation’s **Jorja Fox **is remaining on the case.

The actress has signed a new one-year deal with CBS Television Studios to remain on the long-running procedural, *The Hollywood Reporter *has learned exclusively.

Fox plays forensic scientist Sara Sidle on the CBS drama, a role she first stepped into in the second episode of the Anthony Zuiker procedural in 2000. The actress, who departed the series as a regular in late 2007, returned in May 2008 as a guest star in a handful of episodes. She was later upped to recurring in 2009 and returned to her role as a series regular in July 2011.

Fox’s new deal comes less than two weeks after co-star **George Eads **re-upped with the studio to return for CSI’s upcoming 13th season.

Following a tumultuous season that saw the series uprooted from its longtime Thursday time slot to Wednesdays, the billion-dollar franchise saw **Ted Danson **take over for Laurence Fishburne at the beginning of the season, later being joined by Elisabeth Shue, who replaced Marg Helgenberger. Peri Gilpin made her debut as the wife to Danson’s D.B. Russell during Wednesday’s Season 12 finale, which was up a tenth of a point week-over-week with a 2.4 rating in the key adults 18-49 demographic.

Fox is repped by Domain Talent and Framework Entertainment.
