Tom Pelissero and James Palmer are reporting that Chiefs assistant HC Brad Childress is planning to retire from the NFL.

This comes just a few hours after the Bears announced that they’ve hired Chiefs OC Matt Nagy as their new head coach, so there appears to be serious changes coming to Kansas City’s offensive staff.

Childress, 61, began his NFL coaching career with the Eagles as their QBs coach back in 1999. He spent seven years in Philadelphia before he was hired as the Vikings head coach in 2006.

Childress was fired by the Vikings after five years in Minnesota and he had a brief stint with the Browns before joining the Chiefs’ coaching staff in 2013. He was the team’s offensive coordinator in 2016 before being moved to assistant head coach last year.

During his time as the Vikings’ head coach, Childress led them to a record of 39-35 (52.7 percent), which includes two playoff appearances.
