Sonequa Martin-Green will star opposite Donnie Wahlberg in the upcoming CBS series Boston Blue, which is a spinoff of the beloved hit Blue Bloods.

Donnie is reprising his Blue Bloods role Danny Reagan on the new series after playing the character for 14 seasons on the previous show.

Sonequa‘s casting was announced on Wednesday (May 7) during a CBS press briefing for the unveiling of the network’s 2025-2025 schedule. She will play “detective Lena Peters, the eldest daughter of a prominent law enforcement family, who is partnered with Danny Reagan,” according to Variety.

In a statement, Sonequa said, “We love the Reagans. We have all loved the Reagans for so long. And I feel that we’ll love the Peters too. I’m super excited for this partnership, and to be back in a CBS family — and in this family, your family. It means a lot, and I’m grateful for it. I think we’re going to have a good time.”

Donnie said that Sonequa was the “only choice” for the role of Lena.

“One thing about ‘Blue Bloods’ and how beloved it was is because there are so many law enforcement families in this country. There’s not just the Reagans,” he said. “They’re in every state, every city, every town, everywhere, and there are other families around that have stories to tell too. Danny’s story will continue the Reagan family. You can’t have Danny without Reagans — there’ll be connective tissue. But we’re also going to get to discover a new family and and carry on the tradition of telling their stories.”

Sonequa had her big break on The Walking Dead and starred in the Paramount+ series Star Trek: Discovery.
