The 61-year-old Childress was head coach of the Minnesota Vikings from 2006-10. He first worked in the NFL as a coach over 30 years ago.
Longtime assistant Tommy Brasher Josh Ferguson Jersey , who had spent the past year working on special projects, also announced his retirement in a statement Monday. Brasher spent more than 50 years in coaching.
The Chief announced that longtime linebackers coach Gary Gibbs would not return.
Mark DeLeone will take over inside linebackers with Mike Smith handling outside linebackers. Corey Matthaei will help with the offensive line, Joe Bleymaier will assist with quarterbacks and Terry Bradden will serve as a defensive quality control coach.The Bills' quarterback competition is still unsettled. Their defense showed signs of looking lost in giving up a touchdown pass on the first play from scrimmage against Cincinnati.
And Buffalo's patchwork offensive line is getting manhandled.
These are not encouraging signs less than two weeks before the Bills open the regular season at Baltimore.
"It's a wake-up call for all of us," center Ryan Groy said Monday, a day after the line was pushed around in giving up five sacks in the first half of a 26-13 preseason loss to the Bengals. "We couldn't get anything going. Hurt ourselves pre-snap. Didn't protect the quarterback. Did pretty much of everything on the do-not-do list."
The level of concern was no different on defense after Bengals quarterback Andy Dalton burned Buffalo's defense for 180 yards passing and two touchdowns on five series 鈥?including a 57-yarder to John Ross on the opening snap.
"We couldn't stop them, man," cornerback Tre'Davious White said. "We weren't able to do anything yesterday. They were able to pick their spots and they were able to exploit them."
As for quarterback http://www.chicagobearsteamonline.com/jordan-howard-jersey , coach Sean McDermott is still not ready to name the Bills' season-opening starter, never mind which of his three quarterbacks will start in Buffalo's final preseason tuneup at Chicago on Thursday.
"No further quarterback developments," he said.
Rookie first-round pick Josh Allen's steady progress took a considerable step back against the Bengals. In his first preseason start , he completed 6 of 12 passes for 34 yards, was sacked five times for 39 yards and managed just three first downs over seven-plus series before being pulled to be evaluated for a possible concussion.
Allen was cleared to return for the start of the second half, but remained on the sideline while Nathan Peterman mopped up.
Peterman, Buffalo's returning backup Randy Gregory Jersey , has put up the best numbers this preseason, though he's had just two series against an opponent's starting defense.Moritz Wagner Jersey
