Jason La Canfora of CBS Sports reports that the Bills have fired OL coach Juan Castillo on Tuesday.
Castillo, 59, began his coaching career back in 1982 as the DL and LBs coach at Texas A&M University–Kingsville. He was eventually hired as an offensive assistant for the Eagles back in 1995 and worked his way up to defensive coordinator. Philadelphia would fire him after the 2012 season.
After four years with the Ravens, the Bills hired Castillo as their OL coach and run-game coordinator for the 2017 season.
Football Outsiders have the Bills’ offensive line ranked No. 30 overall in 2018.
