Doug Marrone joins Jags' staff

— -- The Jacksonville Jaguars have hired former Buffalo Bills head coach Doug Marrone to be an assistant head coach for offense and offensive line coach.

Marrone went 15-17 in the past two seasons with the Bills before opting out of his contract earlier this month because of uncertainty over possible organizational changes. The clause in his contract that allowed him to do that also guaranteed his $4 million salary in 2015.

Marrone's hiring means offensive line coach George Yarno will not return to the Jaguars in 2015, according to a team spokesman. The Jaguars announced on May 29 that Yarno had been diagnosed with cancer and he continues to receive treatment. He remains under contract.

Marrone, who went 23-25 as Syracuse's head coach from 2009 to 2012, has coached in the NFL for nine seasons, including three seasons as the offensive coordinator in New Orleans (2006-08).

The Jaguars are still searching for an offensive coordinator to replace Jedd Fisch, whom Bradley fired on Dec. 30. Former Denver Broncos offensive coordinator Adam Gase and former Oakland Raiders quarterbacks coach Greg Olson appear to be the front-runners.

The Jaguars play the Bills next season in London on Oct. 4.
