Grey’s Anatomy has cast former Desperate Housewives actor Steven Culp in a recurring role in the show’s upcoming ninth season.

Culp will play Dr. Parker, a “top dog doctor,” Deadline reports, though it is unclear if he’ll be working at Seattle Grace.

Apart from his role as Rex Van de Kamp in Desperate Housewives, Culp’s credits also include The West Wing and JAG.

Culp joins Friday Night Lights‘ Gaius Charles and True Blood‘s Camilla Luddington as the latest additions to the show. Tina Majorino, known for her roles in Veronica Mars, Napoleon Dynamite and True Blood, will guest star.

Grey’s Anatomy returns with “Going Going Gone” Sept. 27. Catch up on season 8 with the DVD out Sept. 4.
