Blue Bloods might be over but CBS has since expanded the universe with Boston Blue — but which characters are reprising their roles in the spinoff?

Blue Bloods, which premiered in 2010, followed the lives of the Reagan family, many of whom worked for the NYPD under the leadership of NYC police commissioner Frank Reagan (Tom Selleck). Frank’s father, Henry Reagan (Len Cariou), have been central to the show alongside Frank’s children: daughter Erin Reagan (Bridget Moynahan) and sons Danny (Donnie Wahlberg) and Jamie Reagan (Will Estes).

Speculation that Blue Bloods would end started in 2023 when the police procedural was renewed after the cast and producers agreed to take a 25 percent pay cut. Wahlberg exclusively told Us Weekly in April 2023 that he hoped to see Blue Bloods achieve the same level of success as Law and Order: Special Victims Unit.

“I mean, Ice-T and Mariska Hargitay have been going for gosh, so many years, and we hope to last as long as they have,” he shared at the time. “One of the things I’ve done is I try to just stay very present in each episode and take each script that comes my way and say, ‘OK, what’s gonna happen now? You know, what am I doing this week?’ And kind of find the journey in that particular episode and not get caught up in what’s gonna happen next year, what’s gonna happen in two years.”

Wahlberg noted that he wasn’t opposed to the idea of a Blue Bloods spinoff, joking, “Danny and Erin become private investigators and move to Hawaii, but that was too close to [Selleck’s iconic 1980s series] Magnum, P.I., so we didn’t want to do that one.”

After Blue Bloods ended in December 2024, Wahlberg got his wish with Boston Blue. CBS announced in February 2025 that Boston Blue was ordered straight to series and would expand the Blue Bloods universe as Danny “takes on a position” with the Boston P.D.

“It will be a Danny Reagan-based show, but the Reagans are only a phone call away, and Danny Reagan likes to use the phone, that’s all I’ll say,” Wahlberg teased on the “Morning Magic with Sue and Kendra” podcast in April 2025. “I can’t tell a lot of stuff about it other than at this point, I’m very humbled to be producing the show with Jerry Bruckheimer and some incredible writers and producers known as the Brandons. It’s an honor to keep the Blue Bloods tradition alive, and I think that’s what I’ll be doing with the show.”

Danny Reagan

“So excited to carry on the tradition, to share so many surprises, to answer some unanswered questions and to welcome all of you — to #BostonBlue!” Wahlberg wrote via Instagram in March 2025. “The next chapter in the #BlueBloods legacy begins. I can’t wait. See you CBS fall! .”

Erin Reagan

Moynahan is set to star on Original Sound but has previously shown support for more episodes of Blue Bloods.

“I think we’re all a little disappointed,” Moynahan told People in September 2024. “We’ve had such a good time. We all want to be there. It’s a real loss. This was our daily lives for 14 years. And we’ve all experienced together major life moments together, whether it’s births, deaths, marriages, divorces, illnesses, we’ve had it all together.”

It was confirmed in July 2025 that Moynahan will make a guest appearance and direct an episode.

Jamie Reagan

Will Estes is one of many Blue Bloods stars who expressed interest in reprising their role. Wahlberg specifically addressed the speculation, writing via Instagram, “He’d better come visit his big brother.”

Henry Reagan

While Len Cariou hasn’t been announced as a cast member on Boston Blue, he previously expressed disappointment with the OG CBS series coming to an end, telling TV Insider in November 2024, “It’s too bad. Doesn’t make any sense. We’re still, I think, the best-watched show on Friday nights, even though we’re canceled.”

Frank Reagan

Selleck is currently in development on a new installment of the Jesse Stone movie franchise. He hasn’t ruled out a return though.

“I’m open to suggestions, because I love Frank Reagan, but nobody’s really asked,” he admitted to Parade in December 2024. “I don’t see him retiring and going off somewhere.”

Eddie Janko-Reagan

“I would do anything with these people,” Ray told TV Insider in October 2024 about joining a Blue Bloods spinoff. “So, yes, of course. I don’t know what world it would make sense for Eddie to be in a spinoff at all. But if they need to put me in a wig and dye my eyebrows and I’ll play a different character just so I get to hang out with all of them more, then I’ll do it.”

Maria Baez

Marisa Ramirez hasn’t been cast in Boston Blue but has made it very clear that she would return as fans hold out hope for a romance between her character and Wahlberg’s.

Joe Hill

Will Hochman sparked speculation that he would reprise his character after Wahlberg wrote to him via Instagram comments, “@willhochman my guy – counting on you to come visit your uncle on screen!” In response, Hochman replied in March 2025, “@donniewahlberg I’m fueling up the Chevelle as we speak!”
