The Bears are firing offensive coordinator Shane Waldron on Tuesday, nine games into his first season with the team, NFL Network Insider Tom Pelissero reported, per sources.
Thomas Brown, the Bears' offensive passing game coordinator, is expected to take over as OC, per Pelissero.
Chicago has since announced Waldron's dismissal and Brown's promotion.
"After evaluating our entire operation, I decided that it is in the best interest of our team to move in a different direction with the leadership of our offense. This decision was well-thought-out, one that was conducted deliberately and respectfully," head coach Matt Eberflus said in a statement. "I would like to thank Shane for his efforts and wish him the best moving forward."
Amid the three-game skid that's dropped them to 4-5 and last place in the NFC North, the Bears have scored a combined 27 points over the trio of defeats. Their point total has lessoned in each of the three games, and they have not scored a touchdown in 23 possessions.
