In a move no one saw coming, NCIS fan-favorite Brian Dietzen has made a surprising decision that’s left both the show’s crew and longtime viewers stunned. Known for playing the lovable and steady Dr. Jimmy Palmer, Dietzen has been a staple on the series for years. But now, he’s stepping away from the spotlight—at least for a while—leaving fans wondering what this means for the future of his character.

Sources close to the production say the decision came suddenly, though respectfully, and was kept under wraps until recently. While it’s not being labeled a permanent exit, Dietzen is reportedly taking an extended break to focus on personal projects and spend more time with his family. His absence was quietly written into the storyline, catching even the most devoted fans off guard when his character was missing from several key scenes.

Behind the scenes, the crew was said to be emotional but supportive, as Dietzen has been a beloved member of the NCIS family for nearly two decades. Whether this marks the beginning of a slow goodbye or just a temporary pause remains unclear—but one thing is certain: NCIS won’t be the same without Jimmy Palmer.
