The Raiders fired head coach Dennis Allen in September and Tony Sparano coached the team on an interim basis to finish the season.
Del Rio, 51, has been Denver's defensive coordinator for the past three seasons. The Broncos finished No. 3 in yards allowed and No. 16 in points allowed this season.
Prior to joining the Broncos, Del Rio was head coach of the Jacksonville Jaguars for nine seasons from 2003 through 2011. He compiled a 68-71 record before being fired after Week 12 in 2011. He led the Jaguars to a pair of playoff appearances, including a road upset of the Pittsburgh Steelers in the 2007 Wild Card round.
Oakland has been linked to several candidates since the season ended, including a package deal of Mike and Kyle Shanahan. Mike Shanahan previously coached the Raiders in 1988 and 1989. The team has also reportedly interviewed Philadelphia Eagles offensive coordinator Pat Shurmur and San Francisco 49ers tight ends coach Eric Mangini.
The Raiders lost their first 10 games of this season en route to a 3-13 record. They struggled on both sides of the ball, finishing No. 31 in yards gained and No. 32 in yards allowed. They will have the No. 4 pick in the 2015 draft.
