Del Rio, who reportedly "really wants" the Oakland job, interviewed with the Raiders on Sunday. Oakland owner Mark Davis flew in to Denver to personally meet with Del Rio, according to Mike Klis of the Denver Post.
From here forward, Del Rio and Adam Gase, Denver's offensive coordinator who interviewed with the Falcons, 49ers, Bears, and Bills, cannot talk with new teams regarding coaching jobs until the Broncos season is over. Denver could potentially play in three more postseason games. The Super Bowl will be played on Feb. 1.
Meanwhile, former Broncos head coach Mike Shanahan also interviewed with the Raiders, according to Dianna Russini of NBC4. Shanahan was also interviewed by the 49ers.
Shanahan got his first head coaching gig in Los Angeles with the Raiders back in 1988. After clashing with players and the late Al Davis, Shanahan was fired four games into his second season. He was 8-12 with the Raiders.
After a rough tenure with the Raiders, Shanahan went on to help coach the 49ers offense in the early 1990s before being named Denver's head coach in 1995. Shanahan won two Super Bowls with the Broncos before later being fired by Denver in 2008.
Shanahan last coached in Washington before being fired three quarters of the way through the 2013 season. Shanahan owns a 170-138 record as a head coach.
