The Buffalo Bills have hired Aaron Kromer as their new offensive line coach, agreeing to terms on a two-year contract, according to ESPN's John Clayton.

The Bills had been working toward a deal with Kromer over the past few days, and getting it done is a key move for head coach Rex Ryan's staff going forward.

Kromer spent four years as the New Orleans Saints' offensive line coach from 2009-12 before joining the Chicago Bears as the offensive coordinator for each of the past two seasons.
