The Chicago Bears are expected to hire former NFL head coach Brad Childress as an offensive consultant, a league source confirmed Monday.

Childress, the former head coach of the Minnesota Vikings from 2006 to 2010, worked alongside new Bears head coach Matt Nagy in Kansas City from 2013-17. Childress held a variety of titles under Chiefs head coach Andy Reid, including co-offensive coordinator with Nagy for the 2016 season.

"Brad Childress, my partner, we spent five years together,” Nagy said last month during his introductory news conference as Bears head coach. “My partner in crime. Every day he was telling stories and being there for me, being there with me. He has a special place in my heart and I just thank him from the bottom of my heart.”

Childress, 61, announced his retirement following the Chiefs' playoff loss to Tennessee, but the lure of reuniting with Nagy was apparently too great to pass up.

“I think you’re going to see some different things offensively [in Chicago under Nagy],” Childress said last month on ESPN 1000. “I think his record is proven that he’ll do some things differently offensively, and let’s face it, you have to score points to win. I think we [Kansas City] finished fifth in points scored last year.

I know for a fact, because I sat in on the Mitchell Trubisky interviews before the draft with Matt and Coach Reid -- we had him for seven hours -- I know that Matt still has his notes from that interview. He’s very excited about him [Trubisky]. I thought he was a bright-eyed guy. We put him in a tough environment when teaching him plays and making him regurgitate details and specifics. I couldn’t have been more impressed with that guy. But with that said, you got to put guys around that guy. A quarterback can’t do it himself. People always have to play around a quarterback for a quarterback to play well.”

The Bears job is also a homecoming of sorts for Childress, who is a native of Aurora, Illinois, and attended Eastern Illinois University.
