The Raiders are planning a news conference Tuesday to introduce Gruden as their next head coach.
A league source confirmed the information to ESPN's Adam Schefter today.
Gruden, who coached Oakland from 1998 to 2001 and has been working as an ESPN analyst, is returning to the Raiders to replace Jack Del Rio, who was sacked after the regular-season finale on Sunday.
The Oakland Raiders have apparently completed their interview process and decided on their next head coach, and you will never guess who landed the job. His last game with Oakland was the infamous "Tuck Rule" game during the 2002 playoffs that helped launch the Patriots dynasty. He was traded to the Tampa Bay Buccaneers after the 2001 season and led them to the Super Bowl, beating the Raiders 48-21.
ESPN reported that Davis was in hot pursuit for Gruden with a persuasive offer that included an ownership stake in the Raiders.
Current Los Angeles Rams quarterback coach Greg Olson will be Oakland's offensive coordinator, while former Cincinnati Bengals defensive coordinator Paul Guenther will serve in the same capacity under Gruden. Gruden holds an all-time mark of 95-81 over 11 seasons with the Raiders and the Bucs and is 5-4 in the playoffs.
