Fox News left viewers shocked late last month after the network abruptly removed anchor Tucker Carlson from its lineup.

That decision has some conservatives threatening to turn their backs on Fox News, and they include football megastar Brett Favre. 

Favre: "Time to boycott Fox"

According to the Daily Caller, Favre made his displeasure with Fox News known this week when he called for a boycott of the cable channel.

"I’m with Tucker," Favre tweeted on Monday, adding, "Time to boycott Fox until they come to their senses and let the man speak."

Favre included a video clip that showed podcaster and former Fox News host Megyn Kelly arguing that Carlson's removal stemmed from an effort to shut down a controversial figure.

"He needs to be silenced while Fox tries to rebuild that disappearing audience," the Sirius XM host told her followers.

Fox News' viewership down by almost a third

An article published by the Los Angeles Times last week suggests that many television viewers have already adopted Favre's approach.

It cited figures from Nielsen Media Research which showed Fox News' ratings fell by 29.6% in the first week after Carlson's departure.

"Fox News Channel had none of the week’s top 10 cable programs and only three in the 20 — two editions of 'Hannity' and the first edition of 'Fox News Tonight,' the network’s replacement for 'Tucker Carlson Tonight' in the weeknight 8 p.m. time slot," the Times noted.

It pointed out that this represented a sharp decline from the prior week when Fox News held eight of the top 20 spots and two of the top 10, both of which were episodes of "Tucker Carlson Tonight."

Kelly: "Primetime pays the bills"

"They’ve lost almost two-thirds of the audience that helps pay their bills, they’re left without about a third of their audience," Kelly noted.

"I looked up and down the board at the rest of the primetime, which, with respect to the daytime is all anyone gives a s--t about over at Fox News. The primetime pays the bills period. They’re all down," she stressed.
