‘Yellowstone’ Spinoff ‘Y: Marshals’ Delayed — Here’s Why Fans Must Wait
A Longer Wait for Kayce Dutton’s Return
Fans eager to see Luke Grimes back in the saddle as Kayce Dutton will have to wait a bit longer. CBS has officially confirmed that Y: Marshals, the much-anticipated Yellowstone spinoff, won’t premiere this fall. Instead, the series is slated for a midseason 2026 debut.
The show was greenlit in May for the 2025–26 broadcast season, and though filming is underway, the network has opted to hold the series until spring to give it a prime launch slot following established Sunday night hit Tracker.
What ‘Y: Marshals’ Is About
Y: Marshals follows Kayce Dutton as he joins an elite unit of U.S. Marshals in Montana, using his cowboy instincts and Navy SEAL training to deliver frontier justice. The series promises a blend of modern law enforcement drama and rugged Western grit, exploring the “high psychological cost” of serving as the final line of defense in a violent landscape.
CBS will air the show on Sundays at 9 p.m. ET, immediately after Tracker season 3, which premieres on October 19, 2025.
Familiar Faces Ride Again
Alongside Grimes, the cast includes several Yellowstone alumni:
-
Gil Birmingham as Thomas Rainwater
-
Mo Brings Plenty reprising his iconic role as Mo
-
Brecken Merrill as Kayce’s son, Tate Dutton
New additions include Logan Marshall-Green, Arielle Kebbel, Ash Santos, Tatanka Means, and Brett Cullen. While fans hope Kelsey Asbille will return as Monica Dutton, her involvement hasn’t been officially confirmed — yet.
Expanding the Yellowstone Universe
Y: Marshals is one of several Yellowstone spinoffs in development. Other upcoming series include:
-
The Dutton Ranch – focusing on Beth and Rip Wheeler (Kelly Reilly and Cole Hauser)
-
The Madison – starring Kurt Russell, Patrick J. Adams, and Matthew Fox
-
1994 – a prequel connecting to 1883 and 1923
Together, these projects form the most ambitious expansion of the Yellowstone universe to date, ensuring that Taylor Sheridan’s frontier empire continues to dominate screens for years to come.
