Jason George is joining the cast of ABC's upcoming firefighter-focused Grey's Anatomy spinoff as a series regular. He joins an ensemble cast that includes the previously announced Jaina Lee Ortiz as the offshoot's leading lady.

The spinoff, picked up straight-to-series in May, centers on a group of heroic Seattle firefighters from the captain down the ranks in their personal and professional lives. The first episode will air as a planted episode of Grey's, which is set to return Sept. 28 on ABC.

George joined Grey's Anatomy as a recurring player in season six, playing Dr. Ben Warren — the eventual husband to original series star Chandra Wilson's Miranda Bailey. He was promoted to series regular in season 12.

Details about George's transition to the spinoff are being kept under wraps. Just how George will move to the spinoff will be a key part of his storyline on the upcoming 14th season of Grey's Anatomy. George will continue to be a series regular on Grey's season 14 until production of the spinoff begins, at which point he will focus his attention there.

The spinoff marks George's third Shondaland drama after Grey's and ABC's short-lived Hawaii-set medical drama Off the Map. The actor's credits also include ABC primetime serial Mistresses and NBC daytime soap opera Sunset Beach.
