Actor George Eads is leaving "CSI" after 15 years of playing Nick Stokes in the series, according to The Hollywood Reporter.

Eads, who is the last remaining original cast member of the show, will reportedly exit after the fifteenth season. While there have been no statements from CBS and Eads, the split was reportedly amicable.

Eads' exit will affect the resolution of the Gig Harbor Killer case on the show, although details about how his character will be written off have not been released, according to TV Guide, who first broke the news.

The actor's official departure comes after he took a leave of absence last season because of an altercation with one of the show's writers, according to TV Line.

CSI showrunner Carol Mendelsohn reportedly found out about the fight and spoke with Eads about it. Eads threatened to leave the show but decided to leave indefinitely instead of finalizing a resignation.

"George Eads will not appear in several episodes during the first half of the season," according to a statement from CBS at the time. "We look forward to him returning to CSI very soon."

CSI has seen a lot of departures from its cast members in its fifteen seasons on television. William Petersen and Gary Dourdan left the show after the ninth season, while Marg Helgenberger exited after season 12.

Original cast members Jorja Fox and Eads were fired in 2004 after calling in sick on the first day of filming. The move was made in support of the wage hike protest against CBS Television studios.

Eads was taken back as a regular actor, while Fox was demoted to a guest-star post for two seasons before becoming a series regular again for season 11.

The procedural drama will end its 15-year run in 2015 to make way for its spinoff "CSI: Cyber."
