As first hinted at and then ultimately scooped this Saturday by TVGuide.com's Ausiello Report, NCIS creator Donald P. Bellisario is stepping down as show-runner, this on the heels of reports of on-set clashes between him and series star Mark Harmon. Bellisario's duties will likely be assumed by coexecutive producer Chas Floyd Johnson and head writer Shane Brennan.

In a statement, CBS Paramount president David Stapf hails Bellisario, who sired NCIS predecessor JAG, for building not only "a top-rated show but a great producing team that provides terrific continuity for the years ahead."
