Blue Bloods’ Will Estes to Reprise Role on ‘Boston Blue’ Season 2, Donnie Wahlberg Says ‘Welcome Back’

When Boston Blue returns for season 2, there will be another familiar face: Jamie Reagan!

Will Estes, who was a fan-favorite on Blue Bloods, is officially set to make a cameo on the CBS spinoff, according to a new photo shared by Donnie Wahlberg.

“Welcome (back) to the Family! Jamie Reagan! aka Will Estes! #BostonBlue,” Wahlberg, 56, who played Jamie’s big brother Danny Reagan on Blue Bloods before helming Boston Blue, wrote via his Instagram Story on Friday, August 7.

Estes, 47, can be spotted sitting next to Wahlberg as they dined together at a round table.

Boston Blue stars Sonequa Martin-Green, Marcus Scribner, Mika Amonsen, who play Detective Lena Silver, officer Jonah Silver and Danny’s son Sean Reagan, respectively, were also smiling for the camera while on set.

In the background, fans can see some of the camera crew and a few extras that also appeared to be eating a meal for the shoot.

Us confirmed on Friday that Estes will, in fact, be making a cameo on season 2 of the hit drama, making him the third Reagan to crossover from the flagship series.

Fans last saw Estes’ Jamie during the Blue Bloods series finale, which aired in December 2024, when Jamie and wife Eddie Janko (Vanessa Ray) revealed they were expecting their first baby.

After 14 seasons on CBS, Blue Bloods came to a close, seemingly ending the Reagan family’s story — for the time being.

Throughout the series, fans became part of the family as every episode dove into the lives of NYPD Fran Commissioner Frank Reagan (Tom Selleck) and his adult children, Detective Danny (Wahlberg), Assistant District Attorney Erin (Bridget Moynahan) and NYPD officer Jamie (Estes), as they navigated being first responders and a close-knit family.

The show also starred Frank’s father, former police commissioner Henry Reagan (Len Cariou), and his three grandchildren.

Luckily for fans, CBS greenlit Boston Blue soon after the OG show ended. This time, the series follows Danny after he relocates to Boston to help his son Sean — a newly minted BPD officer — after he gets hurt trying to save someone.

Throughout season 1, Danny had to adjust to life in Beantown and quickly found himself assisting on cases as a detective before giving up his shield in NYC to live there full-time.

The cast of Blue Bloods doesn’t just play a family on TV, they’ve become a tight-knit group since the show first premiered in 2010. The CBS series follows the lives of the Reagan family helmed by Tom Selleck’s Commissioner Frank Reagan. Frank’s father, Henry Reagan (Len Cariou), sits opposite him at the group’s weekly Sunday […]

While his family lives in New York, viewers have been treated to a few Reagan crossovers thus far, including Erin (Moynahan) and Pops a.k.a. Grandpa Henry (Cariou).

Danny’s nephew Joe Hill (Will Hochman) and his former NYC partner and girlfriend, Maria Baez (Marisa Ramirez) also popped up during season 1 before they decided to press pause on their relationship.

Although Jamie didn’t appear on season 1, he was part of the story line as was his and Eddie’s baby. During the season finale in May, Danny revealed that Jamie had a little boy named Joseph, after their late brother.

Prior to Estes’ confirmed return, executive producer Brandon Margolis exclusively told Us that the hope is that all the Reagans will make cameos on the spinoff at one point or another.

“It enriches our lives to get to continue their stories,” Margolis shared in May. “So we would love to extend that invitation and have you know new Reagans appear and Reagans who were there last year to come back.”

Season 2 of Boston Blue premieres on CBS Friday, October 9, at 10 p.m. ET.
