When Bears running back Benny Cunningham ran toward the end zone in the second quarter against the Packers and reached out his hands with the football to try and get inside the pylon, the referees ruled on the field that Cunningham had gone out of bounds at about the 2-yard line.

At regular speed, it was a difficult call to make for anyone.

But when the first replays were shown, it was clear that Cunningham had actually lost control of the ball before ever getting to the pylon, which meant that if he DID stay inbounds, then it would be ruled a fumble and the ball would go over to the Packers as a touchback.

After getting advice from his replay staff, Bears coach John Fox threw the challenge flag in the hopes of getting a touchdown and not having to try and score from two yards out. Fox admitted after the game that the touchback possibility never came up during his discussions with his replay crew.

Welp.

Sure enough, the referees agreed with Fox that Cunningham did stay inbounds and fumbled the ball through the end zone, which makes it a touchback.

For a coach already on the hot seat, things turned white-hot on social media.

John Fox has more turnovers today than Brett Hundley. — Chuck Garfien (@ChuckGarfien) November 12, 2017

Give John Fox the turnover chain. — Joe Dolan (@FG_Dolan) November 12, 2017

I’ve been hesitant to join those yelling at John Fox...but that was one of the worst coaching moves. Ever. #Bears — Silvy (@WaddleandSilvy) November 12, 2017

John Fox just challenged that the Bears should get a TD, and it resulted in them losing the ball on a touchback instead. But let’s bring him back. — Tim Baffoe (@TimBaffoe) November 12, 2017

The John Fox Era is going down the drain. #Bears — Rick Morrissey (@MorrisseyCST) November 12, 2017

From now on when a coach's challenge ends up killing his own team it will hereby be called a "John Fox" — Ross Tucker (@RossTuckerNFL) November 12, 2017

Even the Chicago Bears team twitter account recognized Fox’s foibles.

The Bears ended up losing by a touchdown to the Packers, 23-16, and raising more questions about Fox’s future. With the loss, Fox drops to 12-29 (.292) with the Bears. Only Abe Gibron 11-30-1 (.268) has been worse in the history of the franchise.
