The Buffalo Bills have requested interviews with Indianapolis Colts offensive coordinator Pep Hamilton, Cincinnati Bengals offensive coordinator Hue Jackson and Detroit Lions defensive coordinator Teryl Austin, report NFL.com's Ian Rapoport and ESPN's Adam Schefter.
It was previously reported that the Bills are interested in former Jets coach Rex Ryan or promoting defensive coordinator Jim Schwartz, and have also requested interviews with Seahawks offensive coordinator Darrell Bevell, Broncos offensive coordinator Adam Gase, Patriots offensive coordinator Josh McDaniels and Seahawks defensive coordinator Dan Quinn.
Buffalo coach Doug Marrone opted out of his contract on Wednesday after two seasons with the team.
Hamilton has been OC of the Colts since 2013. He previously served as an assistant with the New York Jets, San Francisco 49ers and Chicago Bears and has served as an assistant with Howard and Stanford on the college level.
Austin is in his first season as Lions DC, after spending three seasons as the secondary coach with the Ravens. Detroit head coach Jim Caldwell recently said that he believes Austin is "deserving" of a head coach job due to his work transforming and improving the Lions' defense over the last season.
Jackson is in his first season as Bengals OC, and has also served as their wide receivers coach, secondary coach and running backs coach. The 49-year-old has also been an assistant with the Redskins, Falcons, Ravens and Raiders.
