Tony Terraciano and Andrew Terraciano played Donnie Wahlberg's onscreen sons in Blue Bloods, but where is the actor who played Jack Reagan now after his brother was recast in the Boston Blue spinoff? The CBS series, which premiered in 2010, followed the lives of the Reagan family, many of whom worked for the NYPD under the leadership of NYC police commissioner Frank Reagan (Tom Selleck). Frank's father, Henry Reagan (Len Cariou), was also central to the show alongside Frank's children: daughter Erin Reagan (Bridget Moynahan) and sons Danny (Wahlberg) and Jamie Reagan (Will Estes).
