Fans of Yellowstone have reason to celebrate: Luke Grimes will reprise his iconic role as Kayce Dutton in the upcoming CBS procedural Y: Marshals — a bold shift for the franchise, blending Western grit with law‑enforcement drama businessinsider.com+15cinemablend.com+15laconiadailysun.com+15tvinsider.com. The series, set to premiere in spring 2026, will follow Kayce as he leverages his Montana cowboy background and Navy SEAL training to bring “range justice” to his home turf. Unlike previous Paramount+ series, this spin‑off is slated for network television, airing Sundays at 9 p.m. ET on CBS nypost.com+12ew.com+12thepioneerwoman.com+12.
Who else from Yellowstone might ride alongside Kayce? Grimes teased that “familiar faces” would join him in Y: Marshals . The most likely candidates: his wife Monica (Kelsey Asbille) and son Tate (Brecken Merrill) are strong possibilities, offering emotional depth and continuity from the original storyline countryliving.com+5cinemablend.com+5digitaltrends.com+5.
Using Kayce’s tight tribal relationships, heavy hitters like Chief Thomas Rainwater (Gil Birmingham) and Mo Brings Plenty (Moses Brings Plenty) are also rumored to be recurring characters. Their dynamics could extend beyond Yellowstone, lending weight to his marshal duties through tribal‑law-centered storylines decider.com+15cinemablend.com+15tvinsider.com+15. Meanwhile, lawmen such as Ryan (Ian Bohen) — who already showcased investigative skills in Yellowstone — might join the elite marshal unit, possibly alongside fan‑favorite Jake and Walker nypost.com+14cinemablend.com+14parade.com+14.
Rumors are swirling that even Beth (Kelly Reilly) and Rip (Cole Hauser) could cameo, keeping the Dutton bloodline at the center of the Yellowstone universe. Though they’ll star in their own upcoming spin‑off (Dutton Ranch), brief crossovers remain a possibility businessinsider.com+15cinemablend.com+15digitaltrends.com+15.
Why a marshal series, and why on CBS?
Bringing a series to network TV marks a notable pivot for the franchise. While Yellowstone, 1883, 1923, 6666, The Madison, and the upcoming 1944 have aired on Paramount+, Y: Marshals will expand its reach to a broader audience cinemablend.com+15people.com+15thewrap.com+15. As Paramount’s CEO explained, the franchise “grew from a hit U.S. cable show with 5 million viewers into a global hit with over 100 million fans… and we’re just getting started” people.com.
What story can we expect? The CBS description teases action, moral complexity, and family tension. Kayce’s marshal gig places him in a key role balancing duty and home life in tough‑on‑crime Montana. With familiar producers like Taylor Sheridan and new head Spencer Hudnut (formerly of SEAL Team), the show aims for island‑of‑integrity beats wrapped in broader procedural arcs .
Luke Grimes himself said that while Yellowstone felt like a completed chapter when filming ended, Y: Marshals offered a “very good and interesting” hook he couldn’t ignore . He acknowledged the challenge of returning to Kayce in a new context, yet assured fans that it’s a fresh—and compelling— incarnation reddit.com+6countryliving.com+6cinemablend.com+6.
Where does Y: Marshals fit in the franchise timeline?
This will likely premiere midseason (spring 2026) as CBS replaces The Road with this one‑hour drama parade.com+1thewrap.com+1. All previous Yellowstone content — prequels like 1883, 1923, 1944, and series like 6666, The Madison, and Dutton Ranch — continue expanding the Dutton legacy across centuries and genres, but Marshals is anchored in the contemporary era esquire.com+13people.com+13decider.com+13.
Fan and industry reaction:
Fans are enthusiastically embracing another spin‑off, with many eager to see whether Kayce teams up with Rainwater or Mo in crime‑fighting scenarios. One Reddit user hoped Mo would crash into the storyline:
“Kayce and Mo in a buddy cop show would be badass, and virtually guarantee solid ratings.” thewrap.com+15reddit.com+15cinemablend.com+15
Entertainment outlets have highlighted the novelty of a Yellowstone character leading a traditional network procedural and praised Grimes’ willingness to evolve Kayce laconiadailysun.com.
Bottom line:
Y: Marshals promises to take the heart of Yellowstone—the Dutton family, frontier moral codes, and modern challenges—and funnel it into a new format. With Luke Grimes leading, backed by familiar faces and backed by Taylor Sheridan’s vision, the show aims to be more than a western replay—it’s a range‑country procedural that reflects modern Montana. Fans should gear up for premiere Sunday nights in spring 2026 as the saga gallops onward.
