Here in Chicago, it’s out with one former network newser and in with another.

In a main anchor shake-up, former CBS News correspondent and Chicago news veteran Bob Sirott has signed with WFLD-TV, Chicago’s Fox station, to be its main 9pm anchor. He replaces anchor Jeff Goldblatt, who joined Fox Chicago less than two years ago from his job as a Fox News Channel correspondent.

Ironically, Sirott comes to WFLD about a year after leaving Chicago NBC station WMAQ-TV — where he was succeeded at the anchor desk by yet a third former network guy, ex-Dateline NBC correspondent Rob Stafford. Got all that?

Former Fox News Channel correspondent Jeff Goldblatt — who’s been the 9pm main anchor at Chicago’s Fox O&O WFLD-TV since August of 2008 — is leaving the station, reports vocalo.org’s Robert Feder.

According to Feder, Goldblatt told colleagues his contract would not be renewed later this year. Goldblatt joined WFLD in “a wave of Fox News Channel anchors and reporters drafted for key news positions at Fox-owned stations under big boss Roger Ailes. Among others were Dari Alexander, Rick Folbaum, Greg Kelly, Heather Nauert and Mike Jerrick.”

It’s not known what’s next for Goldblatt. As far as his replacement, Feder cites speculation focused on former CBS News correspondent and Chicago news veteran Bob Sirott.

While cuts have been seen at many major media companies over the last few weeks, News Corp. has stayed largely in the clear. That appears likely to change.

According to a local spy, News Corp. is preparing for a round of cutbacks after the new year, mandating major O&O’s to make “across the board” cuts. Stations like New York’s WNYW, Chicago’s WFLD and Houston’s KRIV are expected to be hit hard.

Our source tells TVNewser some talent contracts are not being renewed, and that any talent who want to renew their deals will be asked to take a pay cut. As for existing talent “balking at signing a pay cut,” our source says, “There’s plenty of good talent on the street looking for work.”

Some former Fox Newsers now at O&O’s include Greg Kelly, Dari Alexander and Rick Folbaum at WNYW and Jeff Goldblatt at WFLD.

CNN was granted permission, and was prepared to spend $100K, for exclusive use of a Skycam.
