Boston Blue Adds to Cast: Here’s Everything We Know So Far About the Blue Bloods Spinoff

Boston Blue is expanding its family with Psych alumna Maggie Lawson, who has joined CBS’ Blue Bloods spinoff, our sister site Deadline reports.

In the offshoot, Donnie Wahlberg reprises his role as NYPD Officer Danny Reagan as he makes the move to the Boston Police Department, where he is partnered with Detective Lena Silver (played by Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family.

Lawson will take on the character of Lena’s “strong-willed and decisive” stepsister, Sarah Silver, who is a Superintendent in the Boston PD. Her position forces her to sometimes walk a tightrope between her job and her family.

In addition to Wahlberg, Martin-Green and Lawson, the ensemble also includes Ernie Hudson in the Tom Selleck-esque patriarch role for the Silver clan. Hudson will portray Lena’s grandfather, Reverend Peters, a renowned and open-minded pastor of a historic Baptist church in Boston.
