When the network broached Boston Blue creators Brandon Sonnier & Brandon Margolis with the idea, they agreed to the change, and then the conversation with Wahlberg began. Wahlberg has long said that he wasn’t ready to put Danny Reagan to bed, so he agreed. And, hopefully, he will have input into the new series so that Danny remains the same Reagan we love.
Here’s everything to know about the Blue Bloods offshoot Boston Blue.
When will Boston Blue premiere?
The Blue Bloods offshoot is scheduled to be released for the 2025-2026 broadcast season.
When will Boston Blue air?
It remains to be seen if Boston Blue will take over the Friday nights at 10 p.m. ET/PT timeslot that did so well for Blue Bloods for 14 years.
Who will star in Boston Blue?
Donnie Wahlberg as Danny Reagan
As of now, it’s unknown why Danny Reagan would move from New York City to Boston to accept a job. But there are a couple of possibilities. We do know that Danny is now an empty nester with his second son, Sean Reagan (Andrew Terraciano), off to college, so he may be looking for something new. His promotability in NYC could be limited because his father Frank Reagan (Tom Selleck) is the NYPD Commissioner. Also, Danny has been a widower for several years, so he may want to find someone new to share his life with, but there’s too many memories of Linda (Amy Carlson) in NYC, which has held him back.

Will any of the cast of Blue Bloods appear in Boston Blue?
The most likely case is that there will be guest star roles for the Blue Bloods cast, but that Wahlberg will be the only series regular. And it may not happen in the first season in order to establish the new show on its own.
What is the plot for Boston Blue?
Danny Reagan moves from New York City to Boston, where he hires onto a position with Boston PD. Once in Boston, he is paired with Detective Lena Peters, the eldest daughter of a prominent law enforcement family.
Is there a trailer for Boston Blue?
It’s way too soon! Other than the pilot, scripts have yet to be written.
How can I watch Boston Blue?
Boston Blue will be available on CBS and stream next day on Paramount+ when the 2025-2026 TV season begins later this year.
