Jack Del Rio and the Denver Broncos have agreed upon a two-year contract that runs through 2015 to remain defensive coordinator.

"Jack did a nice job with our defense," Denver's executive VP of football operations John Elway said. "We had a lot of injuries on that defensive side and Jack did a good job holding that side together. Even in the Super Bowl, our defense kept us in the game in the first half."

Del Rio also served as interim head coach when John Fox underwent heart surgery.
