Although Sean Reagan has followed in the family business on Boston Blue, the actor who originated the role has moved on to other professional endeavors.

Andrew Terraciano, who played NYPD Detective Danny Reagan’s (Donnie Wahlberg) youngest son for Blue Bloods‘ 14-season run on CBS from 2010 to 2024, revealed how he learned he had been recast on the spin-off, which airs Fridays at 10/9c.

“I had somebody call me — actually the day that I was graduating — and they had spoken to my mom and she called me [crying],” he told Us Weekly. “They were like, ‘They might be looking for a different Sean.’ Shortly after we got the news, Donnie called me. It was a really beautiful moment of getting to hear from an old friend but also somebody that you respect so much and have learned so much from.”

In July, Deadline reported that Boston Blue recast the role of Sean with Mika Amonsen, with a source noting the decision stemmed from a new creative direction for the character, pursuing his family’s career path in law enforcement.

“It’s beautiful because you’ll always remember every single line and every day that you had the opportunity to be that character. It doesn’t mean for even a second that somebody else can’t go and do something beautiful with it,” said Terraciano, adding: “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.”
