Hours after the game, the Oakland Raiders made it official by sending out tweet and press release.
This time Gruden will replace Jack Del Rio, who went 25-23 in three seasons with the franchise.
Gruden's 10-year, $100 million contract is the richest in National Football League coaching history and matches Tom Landry and Jimmy Johnson (both with the Cowboys) for the longest, the Times reported.
The announcement comes almost 20 years to the day when Gruden was first introduced as the Raiders' coach.
The Raiders fired Del Rio last week after the conclusion of a 6-10 season.

This could turn into a freezing rain and ice situation and we will be monitoring this storm closely through the weekend. Nonetheless, it'll be the first time in two weeks that many locations saw 30 degrees or better on the thermometer.
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.
All this combined led to the firing of Del Rio at the conclusion of his third season and the fight to get Gruden. For ESPN, Gruden was present for the 2010 Rose Bowl and 2010 BCS National Championship game for ESPN radio. From there he became more involved in commentary, and has been a member of the Monday Night Football crew since 2009 serving as a color analyst.
It's official, Jon, even if the Raiders haven't yet issued a statement.
Gruden was born in Sandusky, Ohio in 1963 and grew up as the son of Jim Gruden, a professional football regional scout, who also served as a running backs coach and director of player personnel on the Tampa Bay Buccaneers.
Gruden's contract extension with ESPN is through 2021, however, he was given a warm send-off from the sports broadcasting company.
