Following its two-part finale that aired on May 11, Watson has entered a new chapter, with CBS outlining plans for the series to return in its 2025-2026 broadcast lineup.

The show, which stars Morris Chestnut as Dr. John Watson, wrapped its debut season with a dramatic confrontation involving James Moriarty, portrayed by Randall Park.

Set in present-day Pittsburgh, Watson reimagines the classic literary figure as the head of the Holmes Clinic of Diagnostic Medicine, where he and his team investigate complex medical mysteries. Described by Chestnut as “doc-detectives,” the characters work both inside and outside the hospital to uncover causes of rare illnesses.

The season’s final episodes introduced Moriarty as the figure behind Sherlock Holmes’ presumed death, a storyline that added intensity and lasting consequences for the clinic’s staff. “By the end, every member of Watson’s team is permanently changed,” said executive producer Craig Sweeny. “And not all the doctors make it to Season 2 as part of the group.”

Although a specific premiere date has not been announced, CBS has placed Watson in its upcoming Sunday night slot at 10 p.m., following the new Yellowstone spinoff Y: Marshals.

Speculation continues around which cast members will return, though Chestnut is expected to reprise his lead role. Season one also featured performances from Eve Harlow, Rochelle Aytes, Inga Schlingmann, Peter Mark Kendall, Ritchie Coster, Riley Orr, and Randall Park.

Despite ongoing questions about Sherlock Holmes’ fate, Sweeny has expressed no current plans to introduce him as a recurring figure. “My belief is that Holmes is gone,” he said. “But I don’t want to be held to that if there’s some great story.”

Watson is available to watch on CBS, with streaming options on Paramount+ and Pluto.
