Actor Jeffrey Dean Morgan, who may be best known as John Winchester on Supernatural, will be joining Julianna Margulies for her hit show The Good Wife.

Deadline reported Morgan will join season seven as a man named Alex, who Margulies’ character, Alicia, hires as an investigator.

The news comes after the show already lost two cast members, including Archie Panjabi, who played Kalinda Sharma. Matthew Goode also left after only being on the show for a year as a regular.

Morgan can also be seen opposite Halle Berry on the summer CBS series Extant. Robert and Michelle King, who are both the creators and executive producers of The Good Wife, said “We’ve loved and admired Jeffrey Dean Morgan for years, and we were thrilled to hear that Julianna did too, so it was a no-brainer to ask him to join our troupe.”

TVLine reported that it could be possible Alex and Alicia may be romantically involved, although it has not been confirmed. Another new face in season seven will come in the form of Cush Jumbo from Torchwood.

The Good Wife returns to television on Oct. 4.
