New Raiders GM Reggie McKenzie will be introduced today, becoming the first Raiders executive to hold the title of General Manager.
McKenzie was rumored to be contemplating whether or not to bring in his own coach.
The 48-year-old McKenzie will fulfill many of the duties once performed by owner Al Davis until his October 8 death at the age of 82.
Jackson, who just completed his first season as head coach after being elevated from offensive coordinator, had been on top of several key personnel decisions in recent months.
He managed to throw together the October trade for quarterback Carson Palmer after starter Jason Campbell broke his collarbone, among other things.
McKenzie will take over his position as Raiders GM effective immediately, meaning he will leave the defending Super Bowl champion Green Bay Packers before they open defense of their title.
Oakland went 8-8 this year after a promising 7-4 start. The Raiders have missed the playoffs for the last nine years since losing in the Super Bowl after the 2002 season.
