CBS's 'Marshals' will not air a new episode tonight, May 31, 2026, as the series is currently on a summer hiatus following the conclusion of its first season on May 24. The show, which expands the Yellowstone franchise, has quickly become the most-watched new series of the year, thanks to its engaging storytelling and strong connection to the original Yellowstone narrative. With its first season wrapping up after 13 episodes, CBS is now preparing for the second season, which has been officially greenlit for a Fall 2026 release. While no specific premiere date has been announced, it is expected to air between September and March. The season finale left fans with intense cliffhangers involving Kayce Dutton and his team, raising anticipation for how the story will unfold in the upcoming season. In the meantime, CBS is filling the Sunday timeslot with reruns of 'Yellowstone' to maintain viewer interest.
