Kayce Dutton’s Next Chapter

CBS has officially greenlit a new “Yellowstone” spinoff centered on Luke Grimes’ character, Kayce Dutton. The 13-episode series, titled Y: Marshals, will explore the youngest Dutton sibling’s journey as he joins an elite unit of U.S. Marshals. Kayce combines his cowboy skills with his Navy SEAL training to bring justice to Montana while navigating family, duty, and the psychological toll of protecting his community.

Filming is set to begin this summer, with the show slated to launch midseason 2026 on Sunday nights. Fans of the Dutton family can expect a familiar mix of high-stakes action, complex relationships, and rugged Western landscapes.

Luke Grimes Reprises Iconic Role

Grimes, who has played Kayce since Yellowstone’s first season, returns to the role with both star power and executive producer duties. When last seen, Kayce had retained a small portion of the Yellowstone Dutton Ranch for his family after selling the majority to the Broken Rock Indian Reservation.

His return promises continuity while opening a fresh narrative arc. Grimes’ experience in action-packed roles — including American Sniper and Fifty Shades of Grey — positions him perfectly to bring depth and intensity to Kayce’s new life as a marshal.

Creative Team Behind the Spinoff

Y: Marshals is written, executive produced, and showrun by Spencer Hudnut, who previously helmed the final seasons of CBS/Paramount+’s SEAL Team. Taylor Sheridan, the mastermind behind the Yellowstone universe, also serves as an executive producer alongside David C. Glasser, Ron Burkle, David Hutkin, Bob Yari, and Grimes himself.

The show is produced by MTV Entertainment Studios, which has handled all prior Yellowstone projects. With seasoned producers and a writer familiar with military and law enforcement storylines, viewers can expect a seamless continuation of the Dutton saga.

CBS Picks Up Where Paramount+ Left Off

Unlike previous Yellowstone spinoffs such as 1883 and 1923, Y: Marshals will air directly on CBS. Amy Reisenbach, CBS Entertainment president, explained that the network aims to make its shows succeed on both linear and streaming platforms. Given the success of Yellowstone and Tulsa King on network television, CBS sees this spinoff as a perfect fit for Sunday night viewers.

Sheridan is continuing to expand the Dutton-verse, with other spinoffs in development. Upcoming entries include a sister series titled The Madison, starring Michelle Pfeiffer, and a show centered on Beth and Rip. This latest spinoff ensures the Dutton family saga remains at the forefront of modern Western drama.

What Fans Can Expect

Y: Marshals promises to mix the intense action and family drama Yellowstone fans know and love. Kayce’s role as a marshal allows the show to explore new territories while maintaining the moral dilemmas and high-stakes tension that define the franchise.

The series will also delve into the personal cost of law enforcement in a lawless region. Balancing his duties with family obligations, Kayce will confront threats both external and internal, forcing him to reconcile his past with the responsibilities of his new life.

The Expanding Yellowstone Universe

This spinoff joins a growing list of CBS series, including Boston Blue, a Blue Bloods spinoff, and CIA, starring Tom Ellis. With multiple Yellowstone prequels and spinoffs in production, the Dutton universe has become a major franchise, promising action, drama, and emotional storytelling for years to come.

As midseason 2026 approaches, fans can look forward to Luke Grimes leading a new chapter of Western justice, exploring loyalty, family, and courage against a backdrop of sweeping Montana landscapes.
