DENVER -- The Denver Broncos and defensive coordinator Mike Nolan have agreed to part ways.
Nolan becomes the third member of coach Josh McDaniels' inaugural staff to depart following a disappointing 8-8 finish. Offensive line coach Rick Dennison left for Houston's staff and longtime running backs coach Bobby Turner was reunited with Mike Shanahan in Washington. Both Dennison and Turner were holdovers from the Shanahan era.

"I can't say anything other than Josh and I mutually agreed to part ways," Nolan said on Monday, according to The Denver Post.

Before the split, Miami sent in a request for permission to interview Nolan, sources close to the situation told ESPN NFL Insider Adam Schefter. Nolan now will talk to the Dolphins about becoming their defensive coordinator.

Nolan, who engineered the Broncos' switch to a 3-4 defensive alignment, was McDaniels' first hire. McDaniels lined up Nolan to help revamp what had been a deplorable defense.

McDaniels said in a statement released Monday by the team: "I have great respect for Mike and wish him success in the future."

As a potential replacement, the Broncos already are discussing former Patriots defensive coordinator Dean Pees, who worked with McDaniels in New England, sources told Schefter.
