Will Boston Blue Recast Season 2 Roles After Cast Change?

Blue Bloods‘ spinoff Boston Blue has already recast one role — but are more changes coming in season 2?

Showrunners Brandon Margolis and Brandon Sonnier addressed the chances of Danny Reagan’s (Donnie Wahlberg) son Jack Reagan making a return after Tony Terraciano stepped back from acting since Blue Bloods. They hinted to TV Insider earlier this month that “it’s possible” that Jack will be referenced again, but didn’t confirm whether that would include the character making an appearance on screen.

Viewers saw Jack and Sean (Andrew Terraciano) grow up in front of their eyes until Blue Bloods premiered in October 2026, when the role of Sean was recast with newcomer Mika Amonsen.

Margolis previously opened up to Us about the chances of involving Andrew in the spinoff — perhaps in a role that nods at his Blue Bloods origins.

“I love that idea. It’s really clever and I think it’s something Donnie would probably be into as well,” he teased to Us two months later. “Because he’s the one always trying to work in New Kids on the Block references. I’m sure Donnie would be open to it. But I think that it’s a very clever idea. If the right opportunities are there, we never say no to a great idea.”

The showrunners also weighed in on finding a way to bring Jack on screen — even if that meant recasting the role.

“Is there a chance? Yes, there is a chance,” Sonnier shared. “We can tell you that there are more family members that will be joining us in the back half of the season. It is an ongoing conversation about various arcs and where we can pay homage, where we can include and where we can expand the universe. We’re huge fans of Blue Bloods and any chance that we get that we can live fully in the universe and include the Reagans is a chance that we jump to take.”

During a December 2025 episode of the CBS series, Danny revealed that Jack was doing Doctors Without Borders in Africa, which was a nod to Tony attending medical school to earn his Doctor of Medicine.

“It’s important to us that we keep the universe alive. We are an expansion of the Blue Bloods universe, and we really, really take that to heart,” Sonnier told Us about the subtle Jack mention. “So we want to check in on the other members of the family. We want to feel like their lives are growing and ongoing outside of the bubble that we see on Boston Blue.”

He continued, “So it is important to us to kind of keep track of where everyone is, where their lives are taking them and hopefully we do get to drop in and visit them in the future.”

Terraciano, meanwhile, expressed gratitude for his time on Blue Bloods.

“It’s beautiful because you’ll always remember every single line and every day that you had the opportunity to be that character,” he shared with Us at the time. “It doesn’t mean for even a second that somebody else can’t go and do something beautiful with it.”

Terraciano celebrated the CBS show, adding, “I got the joy of playing Sean, and I got to send him off into the world. Now somebody else gets that joy. We’re both getting to show what we do and then send Sean off into the world.”

Boston Blue airs on CBS Fridays at 10 p.m. ET.
