‘Boston Blue’: Andrew Terraciano Breaks Silence on Sean Reagan Recasting
What To Know
- Andrew Terraciano spoke about Mika Amonsen replacing him as Sean Reagan in the Blue Bloods spinoff, Boston Blue.
- Co-creator Brandon Margolis previously explained the recasting decision.
- Boston Blue features guest appearances from original Blue Bloods cast members and introduces new characters played.
Blue Bloods star Andrew Terraciano recently broke his silence on Mika Amonsen replacing him as Sean Reagan on Boston Blue.
On Friday, December 5, Terraciano — who played Danny Reagan’s (Donnie Wahlberg) son from 2010 to 2024 on the CBS series — opened up about the recasting choice with Us Weekly.
“It’s beautiful because you’ll always remember every single line and every day that you had the opportunity to be that character,” the 22-year-old said of his time portraying Sean. “It doesn’t mean for even a second that somebody else can’t go and do something beautiful with it.”
Terraciano added of the recasting, “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.”

CBS
In October, shortly after the series premiere of Boston Blue on October 17, co-creator Brandon Margolis explained the decision during an interview with TV Insider.
“We wanted a slightly different version of Sean,” he said. “We wanted a character that feels familiar, an actor that does resemble the character that we watched grow up. But as you saw in the pilot, he has made some life changes and having joined the police force, he is really picking up that family mantle.”
In addition to Wahlberg, other OG Blue Bloods cast members, Marisa Ramirez (Maria Baez) and Bridget Moynahan (Erin Reagan), have made guest appearances on Boston Blue.
The spinoff also stars Sonequa Martin-Green as Detective Lena Silver, Gloria Reuben as Boston District Attorney Mae Silver, Maggie Lawson as Police Superintendent Sarah Silver, Marcus Scribner as rookie cop Jonah Silver, and Ernie Hudson as Baptist pastor Reverend Edwin Peters.

I very classy response to the recasting. Wishing him well in his new endeavors
-
M
Extremely classy and gracious words from the REAL Sean, who should have not been replaced……
-
R
The new actor just isn't Sean and on Blue Bloods Sean never wanted to become a police officer. IThey should have let Blue Bloods have a 2 hour finale to properly end everyone's storylines instead of rushing it off so they could put this show on.
-
J
At one of the family dinners Sean told his grandfather that becoming an officer wasn't out of the question
-
S
I wish that they'd bring Nicky on as a permanent cast member as she also said she wanted to be the first female police officer in the family and TBH it would be great to see that happen although Mom probably would not be too happy about it.
-
-
E
There was at least one or two episodes where he said he wanted to be a cop. So that is not true at all.
-
-
N
They wanted someone more in shape for the role! Shame on them!
The former actor was very gracious by what he said!
Watched the first episode didn’t care for it! They should of stayed in New York!
-
W
Boston Blues doesn't come close to Blue Bloods. It is very contrived. "Danny Reagan" is so out of place in this DEI production.
-
S
Do you have to drag politics into everything? It's just a poor copy of BB. That's it. End of story.
-
-
M
This is true. Original Shawn is not a physical specimen and could not perform action scenes.
-
-
N
Not a fan of Boston blue they’re trying to make it by Blue Bloods by having family dinners. It’s not the same. I think. Danny should’ve taken over the commissioners position when it ended and continue that way my opinion.
-
B
His replacement is a deadwringer for him, minus a few pounds. He dodged a bullet as far as im concerned. I want to like it and have watched the first several episodes but it only gets worse. It's basically a cheap dei knockoff of the original.
-
I
Let me guess! DEI because Danny has (gasp!) a black female partner?
-
D
A few pounds? The old Shawn didn’t have the look for a cop. More like a baker.
-
T
Not to mention that I think he's gay and they didn't want that..
-
-
T
I have to agree..I love Donnie but they are trying to make this a replica of Blue Bloods with the family ties and the dinners but it's not working! The chemistry is not there. I'm surprised it was picked up for a 2nd season.
-
M
Well I guess the network could t rely tell it was a flop after 5 episodes. I can no longer even try to watch it. The characters are stiff, not gelling & Danny doesn't really fit the Boston scene. Call it quits guys. I'll watch my reruns of Blue Bloods.
-
-
C
I want to understand what makes this a dei knockoff? Looking at the other comments so far , one other person called this dei storyline. What exactly is this?
-
-
S
I think he is a class act and maybe they made a mistake not signing him up for this show. Maybe they hired somebody else’s brother Cousin and Place of the real son that played for all those years who knows what the reason is it certainly wasn’t because he wasn’t a good actor because he was
-
B
Where is Danny's other son?
-
J
College

-
M
Well said. I don't believe it, but very nicely done.
-
M
Andrew Terraciano--what a lovely, thoughtful young man. It would have been easy to say unkind things about the show, the replacement or his release. He took the high road. Let's hope we see him again in something new and special. So while I'm here, can we do something about Mr. Wahlberg's new hair style? It just wrong.
-
P
I was a big fan of Blue Bloods, but this show is pretty good, until CBS gives them the boot like all the other great shows!
-
E
Let's be honest here. They recast because the original Sean wasn't fit enough to be a cop. I know that's hard to hear, but it's the truth. It would have been nice to have the original actor, but they did what they had to do for the character. He did give a classy response, so that's nice.
-
D
A very classy response. I’m loving the spin off and family dinners. None of the other shows I watch have those much needed sit downs with family where they talk shop and bond so I’m very glad 😌 they continued that aspect. The first season was good 👍🏽 I’m excited to see what they do with season 2 lets go!!!!
-
M
Blah blah blah don't want to blacklist myself blah blah. Switching him was horseshit and all about his weight.
-
C
Right, Mickie.
-
-
R
The real SEAN takes the high road answering this!! The co-creator failed miserably in his reason why they replaced him. Low blow and for what? Trying to copy the original Blue Bloods? It isn’t working. Feels forced. Not worth the watch. Do better next time.
-
L
Pretty obvious they thought previous guy was too big to play a cop
-
C
I do not think the Boston Blue is very interesting. The story lines do little to show police work like Blue Bloods did. They are trying to make a romance out of the Boston family and Danny and his NEW son. False how quickly they made this romance develop and the family closeness. I am not watching it anymore. Also, be honest about why you changed the sone's role - the son in Blue Bloods was too heavy for the new police role he was to play. You can dance around that all you want, but it is the truth.
Not a good show.
-
O
I call BS We all know why they recasted him
-
B
I always thought Sean was great in BB. They gave him an episode toward the end where he stopped a crime, and I thought he did well being the focus of the whole episode. It was also showing that he had a desire to help people like a cop does. In fact, a friend of mine was overweight (200+) and passed the tests, got thru the academy (Los Angeles) and worked for years—until a car injury on the job and she retired 1/2 pension. So I know for a fact there are police academies that will take heavy cops. There are actually lots of heavy cops, but usually they’ve been on the job a while. But they could have made him getting. Into the academy as a heavy person a plot point. It’s not the old days yet—we’ve accepted woman cops who don’t have men’s physiques, so accepting Sean as a cop is next. There was no good reason to replace Sean.
-
E
I can't see why they recast Andrew Terraciano. Unless Andrew didn't want to make the change, they should have kept him on. His journey would have been perfect.
-
B
I'd like to know the whereabouts of the other son? And will he make an appearance on Boston Blue, I think he was older?
-
B
That was to classy. You should get a lawyer cause we all know why you were recast. Its called body shaming and Im dissapointed that Donny dint fight for this harder. Blue bloods should come back on another network!!
-
S
He is a class act. I am still very sad they replaced him because I was looking forward to watching him grow into his role as police officer.
-
G
At least a young cop! 😉
-
G
I don’t think a NY cop would ever switch sides and become a Boston cop! Never missed a Blue Bloods episode, it’s not the same. Miss all the original family.
-
M
Good response from the original Sean. The dinner scenes don't have the same impact as Blue Bloods. The DEI comments.....wow.....
-
A
I believe that they elected to go with a slimmer version, even though I believe they could of made it work.
-
S
Don't like recast and don't watch the show. If you know Blue Bloods you know that a Reagan wouldn't leave NY and police elsewhere.
-
L
Why not replace Tom Selleck with Bugs Bunny? Donny Walberg with another actor. Hes no Lawrence Olivia. He did the same thing with his first partner. She was sick and they showed her the door. Real family values.
-
M
I think they should’ve used the same Sean
-
S
They could have used that to show how hard it is to actually become a cop and then to help him GET into shape. Being heavy doesn't have to be his end all.
-
S
That is true, but she changed her mind after the episode where she saw just how horrible and hard it is to be a NY police officer.
-
S
I had to laugh at that because it is SO TRUE. Every episode it's different and pretty horrible!!!
-
G
And I presume the fact that the Silver family is Jewish, and Mae has a “mixed race” son – Gasp! Just like some people in real life! – is another reason people want to apply this label.
-
D
You are right, but "Sean" & partner (especially his partner) are crybabies). Jonah Silva character is some seriously BAD at acting. Bring Maria Baez to the show FULL TIME.
-
M
CBS didn't want to pay everybody so they canceled the show and gave one character a spin-off. They did the exact same thing with SWAT.
-
S
Of course, he needed to.say that so he woukd work again
-
T
After having finished watching Boston Blue I can see why they replaced the old Shawn he was too fat. They have the new Shawn jumping over moving cars and tackling suspects. Old Shawn wasn’t fit enough to do all that.’
-
D
What a betrayal!! No way he should be replaced!! How would you like it Donnie??
-
K
Put the original Shawn on there only then will I watch it again that new Shawn cannot act and he stinks
-
D
I think Boston Blue needs to be cancled and bring Blue Bloods back. I wont watch it... Its basically the same show, family cop show, Sunday dinners, the only thing different is the race of the family. I Loved Blue bloods and the cast, but you canceled to basically to remake it just in a different city and cast. I believe you just wanted to cancel Blue Bloods because the cast was basically all white I feel it was a racially motivated move.
-
J
The stars are taken Donny/ Aka Danny, So It's Danny's show., Hey let's have another Stupid game show at night time. When Danny's X Partner Marisa R. Was on So was I For the show a 10, But that was the only show I've watched. Blue Bloods on DVR, But not in Boston. It's not genuine..
-
R
I m not crazy about Boston Blue. They went over board trying to make so diverse. They could have made Blue Bloods more diverse by letting Danny date a African American Erin could have dated a Jewish person Sean could have dated an latino match Frank up with a Asian baptist that's pretty diverse. That's what they did on the other show Boston Blues. They could have gotten a woman mayor. I just don't like the acting or the story lines there's no comparing it to Blue Bloods it falls short.
-
P
I watched the first couple of episodes. It's obvious the show is all about DEI. Bad move on the producers part.
I didn't care for it.
Blue Bloods could have continued
in another form if need be...
and would have been great...
but Boston Blue is not only
not a good show...it's a terrible show.
I give it one season. It won't last.
-
J
I do not care for Boston Blue. I think the show should have stayed in New York. Nothing will replace Blue Bloods.
-
B
Great Show is #1 on Friday Night
-
S
Very diplomatic answers on both sides. The truth is the old Sean couldn’t act his way out of a wet paper bag. That’s the nice way to put it.
