The Chicago Bears lost a potential scoring opportunity when a replay review backfired on coach John Fox during the second quarter of their game against Green Bay.


On third-and-13 from the Packers 25, Benny Cunningham brought in a pass from Mitchell Trubisky and lunged for the pylon while trying to score.


After the replay review, the call was changed to a fumble by Cunningham out of the end zone, giving the ball to Green Bay at the 20.


Fox screamed at line judge Bart Longson after the ruling, and the Soldier Field crowd booed through the ensuing offensive series for the Packers.


Since the Bears "won" the challenge, they did not lose a timeout.
