The Chicago Bears suffered a 29-27 loss to the Pittsburgh Steelers on Monday Night Football last week, and there was quite a bit of controversy surrounding the officiating of the game. The Bears felt they got the short end of the whistle on a number of key calls.

Well, while the NFL is standing behind the controversial Cassius Marsh taunting penalty, the league's officiating department has privately admitted that Tony Corrente and his crew screwed up on several other plays that went against Chicago, per NFL Network's Tom Pelissero and Ian Rapaport.

Perhaps the most notable was a called low-block penalty that wiped out a Justin Fields touchdown pass to Jimmy Graham in the third quarter. A look at the replay shows that James Daniels totally whiffed on his attempted block, but the penalty was called anyway.

Later on that drive, Fields was hit late after a throw but no flag was thrown. The Bears were then forced to kick a field goal on that drive, making it a 14-6 Steelers lead.

Furthermore, several Steelers were lined up in the neutral zone on Cairo Santos' missed 65-yard field goal attempt to win the game. A correctly called penalty would have given Santos another chance from 60 yards, or perhaps Chicago would have sent Fields back out on the field for a Hail Mary attempt.

Instead of a huge win to get to 4-5 on the season to sit just a half-game back of the No. 7 seed in NFC, the Bears are 3-6 and in trouble when it comes to making the playoffs. While Fields looking like a star the last couple of games has been huge for the future of the franchise, it's still a bummer that he was robbed of a signature victory on Monday Night Football.

The NFL likely won't punish Corrente and his crew for these mishaps, but they could get dinged when it comes to postseason assignments.
