The Chicago Bears hired former Minnesota Vikings coach Brad Childress as an offensive consultant and finalized new coach Matt Nagy’s staff.

Childress coached the Vikings from 2006-10 and worked alongside Nagy as a member of Andy Reid’s staff in Kansas City from 2013-17. Childress announced his retirement after the season. But the lure of working with Nagy apparently was strong.

The Bears said Tuesday that Dave Ragone will return as quarterbacks coach [url=http://www.chicagobearsteamonline.com/allen-robinson-jersey]Allen Robinson Jersey[/url] , Charles London will coach running backs and Mike Furrey will coach receivers. The defensive staff returns intact, with Bill Shuey joining as a quality control coach.

The Bears also hired Jason Loscalzo as strength and conditioning coach and Andre Tucker as a trainer.

Chicago announced last month that Vic Fangio would return for a fourth season as defensive coordinator. The Bears also hired former Oregon coach Mark Helfrich as offensive coordinator [url=http://www.dallascowboysteamonline.com/brett-maher-jersey]Brett Maher Jersey[/url] , Chris Tabor as special teams coach, Harry Hiestand as offensive line coach and Kevin Gilbride as tight ends coach.

Chicago fired former coach John Fox after going 5-11 and finishing last in the NFC North for the fourth straight year.

San Francisco newcomer Richard Sherman will miss the next week of training camp and the 49ers' preseason opener after straining a hamstring in practice Friday.

"We're definitely going to rest him at least a week [url=http://www.indianapoliscoltsteamonline.com/marvin-harrison-jersey]Marvin Harrison Jersey[/url] ," 49ers coach Kyle Shanahan said Saturday. "We don't think it should be long term. It's Grade 1, it's a little higher than we expected so we got to be careful with that."

The former Seattle cornerback was hurt chasing down receiver Pierre Garcon after a long completion from Jimmy Garoppolo during a full-team drill. The three-time All-Pro returned to practice at the start of training camp after suffering a torn right Achilles in November with the Seahawks. Sherman signed a three-year $39.15 million deal in the offseason after being cut by Seattle.

In Sherman's place Sunday [url=http://www.indianapoliscoltsteamonline.com/tyquan-lewis-jersey]Tyquan Lewis Jersey[/url] , the 49ers rotated Tyvis Powell and Greg Mabin with the starting defense. Jimmie Ward stepped in for Sherman during the offseason program but has been withheld from full-team drills after suffering a hamstring strain last week. Ward has participated during individual portions of the last two practices.

San Francisco opens its preseason slate Thursday night at home against the Dallas Cowboys.
