Buffalo Bills defensive coordinator Leslie Frazier will interview for the Indianapolis Colts' head coaching job.
The Buffalo News confirmed a report, from NFL Media's Ian Rapoport, that the Colts sought permission from the Bills to interview Frazier. The News also learned, via an NFL source, that permission was granted.
Frazier is one of three candidates for the Colts' top coaching position, which remains vacant after New England Patriots offensive coordinator Josh McDaniels backed out of an agreement to take it Tuesday night.
Other candidates are Philadelphia Eagles offensive coordinator and former Bills quarterback Frank Reich, and New Orleans Saints assistant head coach/tight ends coach Dan Campbell.
Frazier is the only one of the three with full-time NFL head coaching experience. He was named interim head coach of the Minnesota Vikings in 2010 before taking over on a full-time basis from 2011 to 2013. Campbell was interim coach of the Miami Dolphins in 2015.
After spending the 2015 season as secondary coach of the Baltimore Ravens, Frazier joined the Bills a year ago as part of the staff assembled by first-year coach Sean McDermott. The two worked together on the coaching staff of the Philadelphia Eagles. Besides the Ravens and Eagles, Frazier also was a defensive assistant coach with the Cincinnati Bengals, Indianapolis Colts, Vikings and Tampa Bay Buccaneers.
In Frazier's first season, the Bills finished 26th in the NFL in yards allowed, down from 19th in the previous two years. The Bills also ranked 29th against the run and 20th against the pass.
