The Yellowstone universe is expanding once again, and this time it's bringing a fresh face to the Dutton's new frontier. Actor Logan Marshall-Green has officially joined the cast of Y: Marshals, the upcoming spinoff of Taylor Sheridan's hit Western drama, starring Luke Grimes as Kayce Dutton.

Logan Marshall-Green has been tapped as a lead opposite Luke Grimes in CBS’ Yellowstone spinoff series Y: Marshals, in which Grimes reprises his role as Kayce Dutton from Taylor Sheridan’s hit Paramount Network drama.

The series will pick up with Kayce (as played by original Yellowstone star Luke Grimes) as he takes on a new role in an elite unit of the US Marshals, which draws on "his skills as a cowboy and Navy SEAL to bring range justice to Montana".
