Greg Olson will be Oakland's offensive coordinator, Paul Guenther will be defensive coordinator and Rich Bisaccia will coach special teams, La Canfora reports.
NFL Network Insider Ian Rapoport reports that the team is planning to introduce Gruden as their next head coach during a news conference on Tuesday.
ESPN reported that Davis was in hot pursuit for Gruden with a persuasive offer that included an ownership stake in the Raiders.
The Raiders fired head coach Jack Del Rio after the last game of this season, a move seen by many as a big signal that the team's talks with Gruden were serious. During that time, the Raiders won two AFC West titles and advanced to the conference championship once. Gruden spent four years as coach for the Raiders before being dealt to Tampa Bay, where he beat Oakland in the Super Bowl following his first season in 2002.
Kylie Jenner's fans convinced Ellen DeGeneres just confirmed reality star's pregnancy
Khloe Kardashian insists she is in no rush to marry Tristan Thompson , though they have spoken about the possibility of marriage. Ellen than laughed: "No, not you, Kylie is pregnant , I can tell, I will make a bet right now". "I want a "K" or a 'T'".
Sources say Gruden is at a point in his life - his youngest child will be a senior in high school next year - and his broadcasting career ("Monday Night Football" hasn't had the same cache and top games in recent years) where a return to the sideline was more real than ever.
His tenure ended shortly after the "Tuck Rule" loss to the New England Patriots when he was traded the following month to Tampa Bay for two first-round draft picks, two second-rounders and $8 million.
The NFL on Friday said the Raiders have complied with the Rooney Rule in their coaching search. The person spoke on condition of anonymity because the Raiders were not releasing the names of candidates. He came back in 2004 and had a 30-34 record in four seasons, leading Washington to two playoff berths.
