Will Estes is crossing over from the original precinct to Boston. The Blue Bloods alum will reprise his role as Jamie Reagan on an upcoming episode of Boston Blue, the CBS spin-off that launched this fall with Donnie Wahlberg as the lead. Wahlberg teased the guest appearance with a behind-the-scenes photo, captioning it "Welcome (Back) To The Family."
The crossover marks a significant moment for the Blue Bloods universe. Blue Bloods ran for 14 seasons on CBS before concluding in December 2024, and Boston Blue carries forward the franchise's DNA with Wahlberg's Danny "Spellman" Harrington as the central character. Estes played Jamie Reagan, the by-the-book NYPD detective and youngest member of the Reagan family, across the show's entire run.
This guest spot serves as a bridge between the original series and its spinoff. Boston Blue launched with strong viewership as CBS capitalized on Blue Bloods' loyal fanbase. The network positioned it as a continuation of that universe rather than a hard reset, and bringing Estes back underscores that connection. Wahlberg, who spent 13 seasons on Blue Bloods as the show's moral center and comedic relief, anchors the new Boston-set police drama with similar themes of family, duty, and community.
The crossover also signals how CBS plans to leverage its police procedural legacy. With Blue Bloods gone, Boston Blue becomes the network's flagship cop show, and strategic guest appearances from the original cast help maintain continuity and reward longtime viewers. Estes' return as Jamie Reagan gives those fans a direct link to the characters they watched for over a decade.
Details on when the episode airs remain under wraps, but the appearance comes as Boston Blue settles into
