Bears to name Juan Castillo offensive line coach

The Bears acted quickly Wednesday to fill one of their coaching vacancies.

Following the firing of four coaches, including offensive coordinator Mark Helfrich, on Tuesday, Matt Nagy has already made a new addition to his coaching staff.

According to NFL Network's Tom Pelissero, Juan Castillo will join the Bears as their new offensive line coach. Castillo will be replacing Harry Hiestand, who served as Chicago's offensive line coach from 2018-19 and also previously from 2005-09. Castillo is a veteran NFL assistant who also has experience as a running game coordinator,

Castillo most recently served two years as the offensive line coach and run game coordinator for the Buffalo Bills, where he was let go following a disappointing season from his offensive line.

Before his time in Buffalo, Castillo spent four years as an assistant to John Harbaugh with the Baltimore Ravens, where he spent one season as run game coordinator before changing over to offensive line coach.

He worked with Nagy - and under Nagy's mentor, Andy Reid - with the Eagles. He began as the Eagles' offensive assistant in 1995, moved to tight ends coach in 1997 and then coached the team's offensive line from 1998-2010. In a rare move, he became the team's defensive coordinator from 2011-12.
