The Chicago Bears fired offensive coordinator Mark Helfrich and three other coaches on Tuesday, per Adam Jahns of The Athletic.
Offensive line coach Harry Hiestand, special-teams assistant Brock Olivo and tight ends coach Kevin Gilbride were also relieved of their duties.
Chicago finished 29th in points per game this season, one year after owning the No. 9 scoring offense en route to an 11-5 campaign and an NFC North title.
The Bears' 8-8 mark culminated in Chicago's seventh season out of the playoffs over the last eight years.
