Riley Green is making his acting debut on Marshals, and his first episode airs Sunday, April 19. Green plays Garrett, a former Navy SEAL who shows up unexpectedly at Kayce Dutton’s ranch.
Garrett leans on old friends Kayce and Cal as he tries to put the demons of his past to rest. For Green, the CBS drama marks a new step beyond the country stage after he was announced for the role on February 19.
Luke Grimes, who plays Kayce Dutton, said he and Green were working on music together when he came up with the idea to bring him into the show. Grimes said on SiriusXM The Highway on April 3 that he thought it would be cool if Green appeared as an old team buddy, adding that the singer had the look of a team guy and was, in his words, 6-foot-4 and pretty darn handsome.
Marshals stars Grimes as Kayce, who is trying to start over with the U.S. Marshals after the death of his wife, Monica. It is the first Yellowstone spinoff to air on CBS, and its first season also brings back familiar names from the franchise, including Tate, Thomas Rainwater, Mo and Felix Long in Season 1 Episode 6.

Green said in a statement on February 19 that he was excited to join the cast and that being on set with his buddy Grimes made the experience even more memorable. He called it his first trip into acting and said he could not have asked for a better introduction to the world.
The casting gives Marshals a country star with a built-in audience and gives Green a role that fits the image Grimes had in mind. Green built his profile in music beginning in 2018 with his self-titled EP, won the Academy of Country Music’s New Male Artist of the Year award in 2020 and released his third studio album, Don’t Mind If I Do, in October 2024. A deluxe edition is due in August 2025.
For Marshals, the move is a simple one: a show built around hard-edged second chances has now given one to a country singer stepping in front of the camera for the first time.
