Shalev_12.4.jpgTVNewser has learned CBS News boss Sean McManus may be making a change atop his morning show.

Zev Shalev, who has been EP of “The Early Show” since June 2008, may soon be out the door. Multiple sources tell TVNewser that, while Shalev is still on the job, a search is on for his replacement.

We’re told the move may be timed to take advantage of the anchor changes at “Good Morning America.” “The Early Show” has been stuck in third place behind #1 the “Today” show and #2 ABC’s GMA since at least 1987, when people meters began.

Shalev was brought on as a senior producer in March 2008 by then-interim EP Rick Kaplan who had taken over the show after the brief stint of Shelley Ross.

A CBS News spokesperson tells TVNewser, “We don’t comment on rumors. The fact is, we are extremely pleased with the quality and growth of ‘The Early Show’ and look forward to the change in the competitive landscape in January.”
