The television landscape is about to get a powerful new police procedural. Fans of the long-running hit Blue Bloods can mark their calendars: the highly anticipated spin-off, Boston Blue, is officially set to premiere on Friday, October 17, 2025, at 10:00 p.m. ET/PT on CBS, taking over the beloved time slot of its predecessor.
The series is poised to anchor a new Friday night lineup for the network and promises to expand the universe of family and law enforcement drama that fans have cherished for over a decade. Reprising his role as Detective Danny Reagan, Donnie Wahlberg headlines the new show, bringing his signature grit and dedication from the NYPD to the Boston Police Department (BPD). But the move to his hometown doesn’t mean a solo mission; Boston Blue is introducing an entirely new, formidable family of law enforcement professionals—the Silvers—with a stacked cast of television veterans and rising stars.
The New Guard: Introducing the Silver Family
The core of Boston Blue‘s new narrative revolves around the clash of two distinct law enforcement dynasties: Danny’s ingrained Reagan methods meeting the established, politically powerful Silver family in Boston.
Sonequa Martin-Green as Detective Lena Silver
Joining Wahlberg as his new partner is Sonequa Martin-Green (known for The Walking Dead and Star Trek: Discovery) as Detective Lena Silver. Lena is described as a “rising star” and the eldest daughter of the Silver family, representing the best and brightest of the BPD. Her partnership with the more seasoned, old-school Danny Reagan is set to be a central tension of the series, providing a rich dynamic of mutual respect, but frequent conflict, as they navigate the city’s complex cases.
Ernie Hudson as Reverend Edwin Peters
Taking on the role of the Silver family patriarch is the legendary Ernie Hudson (Ghostbusters). Hudson plays Reverend Edwin Peters, the family’s spiritual and moral compass, a respected pastor of a historic Baptist church in Boston. This character is clearly designed to fill the void left by Frank Reagan (Tom Selleck), serving as the grounding, open-minded figure who presides over the family’s weekly Sunday gathering—the Boston counterpart to the Reagan family dinner.
Gloria Reuben as Mae Silver
Veteran actress Gloria Reuben (ER, Mr. Robot) joins the cast as Mae Silver, Boston’s District Attorney and the matriarch of this blended law enforcement family. As the widow of a judge, Mae’s commitment to justice runs deep, and her position as D.A. will naturally put her in professional tension with her daughter, Detective Lena Silver, echoing the beloved dynamic between Danny and his sister, Erin Reagan.
Maggie Lawson as Superintendent Sarah Silver
The Silver family’s influence extends to the top of the BPD hierarchy with Maggie Lawson (Psych) cast as Superintendent Sarah Silver. As Lena’s stepsister and a commanding figure in the Police Department, Sarah’s decisions will directly impact Danny and Lena’s work on the street, introducing a new layer of internal police politics and family accountability.
Marcus Scribner as Rookie Cop Jonah Silver
The youngest generation of the Silver family is represented by Marcus Scribner (Black-ish) as Jonah Silver, a rookie patrol cop. Jonah is Lena’s younger brother, eager to prove himself but naturally frustrated by his rookie status on the sidelines of major investigations. His story will parallel the early career experiences of Jamie Reagan, highlighting the challenges of starting out in a high-stakes, family-run profession.
The Reagan Connection: Returning to Boston
The move to Boston for Detective Danny Reagan is fueled by more than just a job transfer; it’s a deeply personal homecoming. The series is set to follow Danny as he attempts to reconnect with his youngest son, Sean Reagan, who, in a significant change from Blue Bloods, is now a Boston PD patrolman.
The role of Sean Reagan has been recast with Mika Amonsen taking over from the original actor, Andrew Terraciano. This change underscores the show’s intention to firmly establish a new identity while maintaining the foundational connection to the Reagan family legacy.
In a move sure to delight fans, Bridget Moynahan will reprise her role as Danny’s sister, Erin Reagan, for a special guest appearance in the series premiere. This cameo helps bridge the transition from New York to Boston and ensures the Reagan family spirit is carried forward into the new series. Moynahan is also slated to step behind the camera, directing an episode of the spin-off, demonstrating a continued commitment to the Blue Bloods universe.
The Premiere and What to Expect
Boston Blue will have its official CBS premiere on Friday, October 17, 2025, at 10/9c. The pilot episode, titled “Faith and Family,” will see Danny and Lena tackle their first case together, investigating a deadly fire at a tech company. The official synopsis teases that this initial case will uncover “a complex web of secrets involving facial recognition technology, family ties, and a search for justice that brings the Silver and Reagan families closer together.”
The show’s plot is a masterstroke of procedural drama, blending high-stakes crime with the beloved family conflicts that made Blue Bloods a hit. Danny Reagan will find himself an outsider for the first time in his career—a lone Reagan in a city dominated by the Silvers. The new series aims to explore themes of tradition versus change, and the pressures of carrying a family legacy in a city with its own entrenched history.
Boston Blue is set to continue the legacy of CBS police dramas, with the guarantee of strong character work, gripping crime solving, and the kind of authentic family dynamics that resonate with a massive audience. With an all-star cast and a confirmed fall premiere date, the countdown to Danny Reagan’s new chapter is officially on. Get ready for an all-new law and order experience, Boston style!
