(SportsNetwork.com) - Seattle Seahawks defensive coordinator Dan Quinn has agreed to a five-year contract to become the Atlanta Falcons' next head coach, according to multiple reports.
The Atlanta Journal-Constitution reported that Quinn, whose units in Seattle yielded the fewest yards and points in the NFL over the past two seasons, will be formally introduced at a news conference scheduled for Tuesday.
Quinn's hiring was regarded as an inevitability, with the Falcons having no problem waiting until the Seahawks completed their run to Super Bowl XLIX before making the move official.
Atlanta, which fired head coach Mike Smith after the team concluded a second consecutive losing season in late December, had previously interviewed Quinn twice for the job before making the 44-year-old its top choice.
Quinn emerged as a sought-after candidate by constructing a Seahawks defense that allowed just 14.4 points and 273.6 total yards per game during the 2013 season, which the group capped with a dominant performance in Seattle's 43-8 rout of the Denver Broncos in Super Bowl XLVIII.
It was Quinn's first season as an NFL defensive coordinator, though he previously served in that role at the University of Florida for two years prior to returning to Seattle. Quinn was the Seahawks' assistant head coach and defensive line coach from 2009-10.
The Seahawks were equally as strong on the defensive side this past season. Seattle permitted 15.9 points and 267.1 yards per game en route to a second straight NFC title.
According to NFL.com, the Seahawks will promote defensive backs coach Kris Richards to defensive coordinator in Quinn's place.
Former Cleveland offensive coordinator Kyle Shanahan is expected to join Quinn's staff as the primary play-caller. Shanahan resigned from the Browns following the conclusion of this past season over differences with the team's front office.
