New York: The Boston Blue Season 2 casting news has delivered a major surprise for Blue Bloods fans. Will Estes is returning as Jamie Reagan in the second season of CBS crime drama Boston Blue, bringing another familiar face from the original series into Donnie Wahlberg’s new chapter.
Estes will guest-star in Season 2, reuniting with Donnie Wahlberg, who continues to play Danny Reagan. Wahlberg himself revealed the reunion through an Instagram Stories post on August 7, welcoming Estes back to the Reagan family. CBS has also confirmed Estes’ guest appearance.
The announcement is particularly important because Jamie and Danny are brothers in the Blue Bloods universe. Their reunion gives Boston Blue another direct connection to the original 14-season CBS drama.
What Happened?
The biggest development is simple: Will Estes is coming back as Jamie Reagan for Boston Blue Season 2.
Estes played Jamie throughout all 14 seasons of Blue Bloods, where his character developed from a young police officer into a key member of the Reagan family. His return marks another significant crossover between the original series and its Boston-set spin-off.
Wahlberg shared a photo featuring himself, Estes and several current Boston Blue cast members. His message welcomed Estes “back” into the family and identified him as Jamie Reagan. CBS subsequently confirmed to Entertainment Weekly that Estes will guest-star during the second season.
However, there is an important detail fans should keep in mind: the storyline for Jamie’s appearance has not been revealed yet. Neither CBS nor the production team has announced how many episodes Estes will appear in or exactly why Jamie travels into Danny’s new Boston-based story.

Latest Update on Boston Blue Season 2 Casting
Will Estes is not the first Blue Bloods veteran to appear in Boston Blue. The first season already brought back Bridget Moynahan as Erin Reagan and Len Cariou as Henry Reagan. Their appearances helped establish that the spin-off could continue to explore different branches of the Reagan family.
Estes’ return takes that connection a step further because Jamie is Danny’s younger brother. That relationship gives the writers an opportunity to create a more personal storyline rather than simply using another familiar character for a brief cameo.
There has also been previous discussion from Boston Blue co-showrunner Brandon Sonnier about bringing more members of the Reagan family into the spin-off. In December, Sonnier teased that additional Reagans could appear, including characters viewers had not yet seen in the show.
For now, Estes is officially confirmed as a guest star. Any further claims about Jamie becoming a regular character, appearing in multiple episodes or bringing other characters with him should be treated as speculation until CBS announces more.
Release Date and OTT Platform
Boston Blue Season 2 is scheduled to premiere on Friday, October 9, 2026, at 10 p.m. ET/PT on CBS. CBS announced its fall 2026 premiere schedule with Boston Blue returning to the Friday night lineup.
The series is also part of CBS’s streaming lineup on Paramount+. CBS states that its shows are available through the CBS Television Network and on Paramount+, with availability depending on the subscriber plan.
The original Boston Blue format centers on Danny Reagan after he leaves New York and takes a position with the Boston Police Department. He works alongside Detective Lena Silver, played by Sonequa Martin-Green, while also attempting to reconnect with his son Sean.
CBS ordered a second season in December 2025. At the time, the network described Boston Blue as its No. 1 new series, citing an average of about 8 million viewers in Nielsen live-plus-seven-day multiplatform ratings.
Cast, Story and What to Expect
Donnie Wahlberg remains at the center of the series as Danny Reagan, while Sonequa Martin-Green returns as Detective Lena Silver. The main ensemble also includes Maggie Lawson as Sarah Silver, Marcus Scribner as Jonah Silver, Mika Amonsen as Sean Reagan, Gloria Reuben as Mae Silver and Ernie Hudson as Reverend Edwin Peters.
The addition of Will Estes gives Season 2 another connection to the Reagan family without changing the show’s primary Boston setting.
The first season established Boston Blue as an expansion of the Blue Bloods universe rather than a direct continuation of the original show’s New York setting. Danny is now adjusting to Boston, his new police role and his relationship with the Silver family.
What Jamie’s arrival means for Danny has not been officially disclosed. The Season 1 finale did, however, establish a new family detail involving Jamie and his wife Eddie’s son, Joseph, named in honor of Danny’s late brother. That development could provide context for Jamie’s return, although CBS has not confirmed whether it will be central to his Season 2 appearance.
What Fans Are Saying
The announcement has already generated discussion among Boston Blue and Blue Bloods fans online. A Reddit discussion following Wahlberg’s post featured many positive reactions to seeing Estes return, with several fans describing the development as another step toward bringing the Reagan family together.
At the same time, online fan comments should not be confused with official story information. Some viewers are already speculating about which other Blue Bloods characters could appear in Season 2, but there is currently no official confirmation that every returning-character theory will happen.
The strongest confirmed news remains Estes’ guest appearance as Jamie Reagan.
