"Supernatural" co-showrunner Sera Gamble is exiting the helm of The CW drama series, according to Deadline.

Gamble, who been with the show since Season 1, is leaving to focus on development opportunities. She was serving alongside co-showrunner Robert Singer for the past two seasons following the departure of series creator Eric Kripke in 2010.

Replacing Gamble is Jeremy Carver, who served as a co-producer on "Supernatural" during the 2009-10 season before leaving to take on executive producing and co-showrunning duties on Syfy’s "Being Human" alongside his wife Anna Fricke.

Carver will co-run the series with Singer during Season 8, which The CW is expected to green light.

"Supernatural" follows the high-stakes struggle of two brothers, Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles), who hunt and destroy monsters and the forces of darkness.

Despite his new responsibilities, Carver will keep his executive producer credit on "Being Human" while Fricke assumes full control of the series.

Kripke remains attached to "Supernatural" as an executive consultant.
