Packers HC Matt Lafleur announced four new coaching changes on Thursday.
Jason Simmons has been promoted to defensive backs coach, and Ryan Downard to assistant defensive backs coach. Jerry Montgomery and Ben Sirmans have been retained as defensive line coach and running backs coach respectively.
Simmons, now in his ninth year with the Packers, will take over the defensive backs coaching spot. After playing in the NFL for ten seasons, he became a coaching administrator for the Packers in 2011, was promoted to a defensive/special teams assistant in 2014, and was the assistant special teams coach from 2015-2017.
