The Bills have reached a two-year deal with former Bears offensive coordinator Aaron Kromer to be the team's new offensive line coach, John Clayton of ESPN reports on Saturday.

Kromer spent the last two seasons as the offensive coordinator in Chicago. The Bears ranked 15th in passing yards (237.0) and 27th in rushing yards (90.1) last season. Prior to that, he was on the Saints coaching staff for five season, serving as the team's interim head coach for the first six games of 2012.

Lee spent 2012 as the Bills' quarterbacks coach and has extensive experience coaching the position in the college ranks.
