The Buffalo Bills' hunt for their next head coach might not extend beyond the building.

After firing Rex Ryan on Tuesday, the Bills made offensive coordinator Anthony Lynn their interim head coach. And, according to Vic Carucci of The Buffalo News, they have all but settled on giving Lynn the job on a permanent basis.

Carucci writes that there is "every indication" that Bills general manager Doug Whaley, who is expected to retain full control over the team's 53-man roster, will promote Lynn on a permanent basis.

Lynn is willing to work under Whaley despite the latter's broad control, a situation many other head coaching candidates wouldn't be open to, according to Carucci.

Lynn began the season as the Bills' running backs coach, and was promoted to offensive coordinator following Greg Roman's firing in mid-September.
