Sonequa Martin-Green Joins Donnie Wahlberg in 'Boston Blue', the Anticipated Blue Bloods Spinoff

As previously reported, CBS has started a Blue Bloods universe with the spinoff Boston Blue (release date unknown at this time). Donnie Wahlberg will continue his role as Detective Danny Reagan as his moves to Boston to continue being a boy in blue. Joining him as a new series lead is Sonequa Martin-Green. The two stars made the news official at a CBS press event unveiling the 2025-26 network schedule, and the chemistry between them was undeniable.

A Bold New Chapter for Danny Reagan

In Boston Blue, Danny Reagan makes a pivotal career move, leaving behind his New York City roots and his iconic Reagan family to join the Boston Police Department. It’s definitely a change the hardened New York detective, who will have to adjust not only to a new city but also to a new partner, Detective Lena Silver, played by Martin-Green.

"Danny does not like Boston very much, as we’ll discover," Wahlberg quipped during the announcement. "He’s a New Yorker, he’s a Mets fan and a Jets fan…" That built-in tension and back-and-forth banter between the two characters will be interesting to see.

Sonequa Martin-Green Brings Strength and Sophistication to Detective Lena Silver

Sonequa Martin-Green, is a star in her own right. We loved her in Star Trek: Discovery and The Walking Dead, as she steps into the role of Detective Lena Silver, the eldest daughter of a prestigious Boston law enforcement family, we are on pins and needles waiting for first looks.

“You’re going to have a lot of fun poking fun at me,” Martin-Green joked to Wahlberg at the press event. “And I’m going to have to get a really good Boston accent just so I can like throw it out at times!” Her addition to the cast signals a strong black female lead presence and opens the door to exploring the legacy of a new law enforcement family, the Silvers.

Familiar Roots with New Faces

While Boston Blue breaks new ground, Wahlberg was quick to reassure loyal fans of the original series. “Danny’s story will continue the Reagan family’s,” he confirmed. “You can’t have Danny without Reagans.”

Though set in a new city, Boston Blue will maintain “connective tissue” to the original Blue Bloods, promising appearances or mentions of fan-favorite characters, and perhaps even crossovers. “We are really working on this universe in a way that I think the Blue Bloods viewers are going to be very happy,” Wahlberg said.

Production Begins This Summer

Boston Blue is slated to begin filming in late summer 2025, with an official release date yet to be announced. Anticipation is high, and with a powerhouse cast and rich narrative potential, CBS appears poised to deliver another hit.

As Blue Bloods enters a new era, Boston Blue promises to blend the grit and family dynamics that fans love with new characters, fresh conflicts, and a different city’s flavor.
