Boston Blue is one of the most-watched new shows of fall 2025, and CBS has officially renewed the Blue Bloods spinoff for a second season. The network renewed Boston Blue and its other new Friday drama, Sheriff Country (a Fire Country spinoff), on Wednesday, December 3.
Boston Blue follows Donnie Wahlberg‘s Blue Bloods character, Danny Reagan, as he and son Sean Reagan (Mika Amonsen) make a new life for themselves in Boston. They’ve become close friends with Boston’s prominent law enforcement family, the Silvers, and Danny’s new partner is Detective Lena Silver (Sonequa Martin-Green). Six episodes have aired so far, and now we know there will be more.
“Two new shows on Friday night have become instant hits with audiences quickly embracing Boston Blue and Sheriff Country across broadcast and streaming,” said Amy Reisenbach, President of CBS Entertainment. “These early renewals reflect the power of character-driven storytelling, compelling narratives, and the exceptional talent on both sides of the camera that make these series truly stand out.”
