Will Kevin Costner Appear on ‘Y: Marshals,’ the Upcoming ‘Yellowstone’ Spinoff?

The Spinoff Storyline

Y: Marshals, premiering March 1 on CBS, continues the Yellowstone universe with Kayce Dutton (Luke Grimes) stepping into a new role as a U.S. Marshal. The spinoff explores how Kayce’s moral compass and lawman instincts evolve beyond the ranch life that defined much of his story in Yellowstone.

The series blends classic Western grit with U.S. Marshals procedural action, setting a tone that mixes rugged landscapes with modern justice themes.

Returning Faces from Yellowstone

Several familiar characters from Yellowstone are officially confirmed to return, keeping continuity with the flagship series. Producers have hinted that additional appearances may occur, allowing deeper crossover moments that connect Y: Marshals to the Dutton legacy.

Kevin Costner’s Involvement

As of now, Kevin Costner’s (John Dutton) participation remains unconfirmed. Although Costner departed Yellowstone before its concluding episodes, fans continue to speculate whether his iconic role could make a brief reappearance or provide closure through archival footage or flashbacks.

Showrunners have neither confirmed nor denied any plans to feature John Dutton, choosing instead to focus on Kayce’s journey as he forges his own identity apart from his father’s shadow.

Franchise Outlook

The Yellowstone universe continues to expand under Taylor Sheridan’s creative direction. Y: Marshals joins a growing list of spinoffs, building on the generational storytelling that began with the original series and its prequels like 1883 and 1923.

“Fans will find familiar heart and values in this new chapter,” said a CBS representative, describing the project as both standalone and deeply connected to the Dutton saga.

Author’s summary: The Yellowstone spinoff Y: Marshals follows Kayce Dutton as a U.S. Marshal, with familiar faces returning and Kevin Costner’s potential cameo still uncertain.
