CBS crime drama Blue Bloods may have ended, but its legacy will continue this fall when spinoff Boston Blue arrives on Oct. 17 2025 in the franchise’s Friday‑night slot.
The network confirmed the date while announcing that Bridget Moynahan will reprise assistant district attorney‑turned‑public‑servant Erin Reagan in the premiere. Deadline first reported Moynahan’s return, and the actress appeared in a Boston PD jacket beside Donnie Wahlberg in his Instagram reveal.
Variety’s social‑media feed recorded thousands of likes on the photo within hours, underscoring the Reagan family’s staying power. Moynahan will also direct an episode, extending the behind‑camera experience she gained late in the original series run.
While the guest spot reconnects viewers with New York’s Reagans, Boston Blue introduces an ensemble led by Sonequa Martin‑Green, Maggie Lawson, Marcus Scribner, Gloria Reuben and Ernie Hudson as members of Boston’s influential Silver family.
People confirmed that Mika Amonsen will assume the role of Sean Reagan—last seen in high school—now a patrol officer whose relocation convinces his father to remain in Massachusetts.
Showrunners Brandon Sonnier and Brandon Margolis frame Sean’s badge as the hinge between old and new storylines. Filming began this month in Toronto, with location shoots planned for Boston later in the summer.
