John Fox's challenge accidentally results in Bears turnover

In what'll go down as the most unfortunate challenge of the season, Chicago Bears head coach John Fox accidentally stripped his own team of possession a yard shy of the end zone and gave the ball to the Green Bay Packers.

Fox threw his red flag when Benny Cunningham was ruled out of bounds right before diving for the corner of the end zone. Fox argued that Cunningham had crossed the plane, which would've resulted in a touchdown, before he went out of bounds.

However, the officials determined upon review Cunningham actually fumbled the ball out of the end zone - and did so before he went out of bounds - thereby resulting in a touchback and possession for the Packers.

In other words, Fox would've been a lot better off just standing on the sideline and doing nothing.
