CBS’s upcoming “Blue Bloods” spinoff has recast Danny Reagan’s son after the same actor played the recurring role throughout the original 14 seasons. Andrew Terraciano will not return as Sean Reagan in “Boston Blue” after appearing in nearly every episode across 14 seasons as the son of Donnie Wahlberg’s character,

Mika Amonsen ( Thanksgiving) has joined the show’s cast as Sean Reagan, the youngest son of series lead Donnie Wahlberg’s character, Danny Reagan. Amonsen will take over the role played by Andrew Terraciano throughout Blue Bloods’ 14-season run on CBS.

Terraciano, 22, appeared in all but one of the 293 episodes of the primetime network show Blue Bloods. Siblings Sean and Jack Reagan were played by real-life brothers Andrew and Tony Terraciano -- who parted ways with the show in season 9 in pursuit of a medical career.
