Former Raiders head coach Jack Del Rio is a leading candidate to become Pat Shurmur's defensive coordinator with the New York Giants, league sources told ESPN's Chris Mortensen.

Del Rio has been prominent on Shurmur's list of defensive candidates, and he is open to joining the presumptive Giants coach.

The Giants are planning to schedule a second interview this week with Shurmur, sources told ESPN. If Minnesota loses to the Eagles in Sunday's NFC Championship Game, the Giants can negotiate or sign Shurmur immediately.

Del Rio won't be doing it for money if he becomes the Giants' defensive coordinator. He is scheduled to average $6 million per year from the Raiders over the next three years, and any salary he is paid by the Giants simply will be offset against his Oakland contract, sources tell Mortensen.

Del Rio was fired after a season-ending 30-10 loss to the Chargers. The Raiders went 6-10 this past season, and Del Rio finished his stint in Oakland with a 25-23 regular-season record. The Raiders won just 13 games in the three seasons before he arrived.
