Will Frank Reagan return for Blue Bloods spinoff? Tom Selleck & Donnie Wahlberg aren’t on same page

The future of Frank Reagan in Boston Blue is still uncertain — and recent comments from both Tom Selleck and Donnie Wahlberg suggest they may not fully agree on how — or even whether — Frank should return.

According to a recent CinemaBlend report, Wahlberg sounds optimistic that Frank Reagan will eventually appear in the Blue Bloods spinoff Boston Blue. Speaking at CBS Fest, Wahlberg said:

“When the time is right, I’m sure we’ll find something to do together.”

He emphasized that Selleck supported the creation of the series and suggested the main obstacles are timing, scheduling, and finding the right script. (Cinemablend)

But Selleck’s public comments have been noticeably more cautious.

In earlier interviews covered by CinemaBlend and IMDb coverage IMDb News, Selleck indicated he’s hesitant to return unless the story truly makes sense for Frank Reagan. Reports suggest he wants to preserve the character’s legacy rather than bring him back for a brief cameo or nostalgic appearance. (Cinemablend)

That difference in tone is why fans think the two stars “aren’t on the same page.”

Wahlberg talks about Frank’s return as something that will probably happen eventually. Selleck, meanwhile, sounds far more selective and noncommittal. (Cinemablend)

What makes the situation even more interesting is that Boston Blue has already brought back several Reagan family members from Blue Bloods — including Bridget Moynahan and Len Cariou. (Cinemablend)

That makes Frank Reagan’s absence feel even more noticeable to viewers.

Fans online have increasingly speculated that the show is intentionally delaying Frank’s appearance to make it a major emotional event later — possibly during a Season 2 storyline. Others worry Selleck may never fully return because he appears interested in exploring different roles after spending 14 years as Frank Reagan. (Cinemablend)

For now, CBS has not officially confirmed any appearance by Selleck in Season 2.

Still, Wahlberg continues publicly leaving the door open, and the show itself keeps referencing Frank’s influence on the Reagan family. A recent episode even featured Danny and Erin discussing lessons their father taught them during childhood, reminding viewers that Frank remains emotionally central to the franchise even when off-screen.

So the short answer is:

Frank Reagan could return to Boston Blue — but at the moment, Donnie Wahlberg seems far more confident about it happening than Tom Selleck does.
