Yellowstone Star Luke Grimes Returning for Sequel Series: All the Details

Luke Grimes is stepping back into Kayce Dutton’s boots.

The Yellowstone actor—who portrayed the son of Kevin Costner‘s John Dutton III—will reprise his role from the flagship show in a new series tentatively titled Y: Marshalls, CBS has announced. 

“With the Yellowstone Ranch behind him, Dutton joins an elite unit of U.S. Marshals,” the network said in a May 7 statement, “combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.”

The new Yellowstone spinoff—one of several in the hit franchise—is set to premiere on CBS in the 2025-26 midseason and air Sundays at 9 p.m. Grimes and franchise creator Taylor Sheridan will both serve as executive producers along with several others, including Spencer Hudnut, who will also work as the showrunner.

“Cowboys dont say goodbye,” Grimes wrote May 7 on his Instagram about the new series, “they say see you later.”
