Matt LaFleur, who worked under 49ers coach Kyle Shanahan in stops in Houston, Washington and Atlanta, was hired Monday as head coach of the Green Bay Packers, according to multiple reports.

LaFleur’s younger brother, Mike, serves as the 49ers’ wide receivers coach and passing game coordinator. Mike LaFleur previously worked under Shanahan in Cleveland and Atlanta.

It is not believed the LaFleur brothers will reunite with the Packers at this stage of their careers. Mike LaFleur was given the title of a coordinator after last season, and appears to be happy as one of Shanahan’s top offensive assistants. He remains under contract to the 49ers beyond this season.

Matt, 39, and Mike LaFleur, 31, worked together for two seasons with the Atlanta Falcons. Matt was the Falcons quarterbacks coach. He was hired as offensive coordinator on Sean McVay’s staff with the Los Angeles Rams in 2017. After one season with the Rams, Matt LaFleur left to become Tennessee Titans offensive coordinator.

Mike LaFleur joined Shanahan in Cleveland in 2014 as a coaching intern – a position his brother, then an assistant at Notre Dame, accepted for him on his behalf. Mike LaFleur worked with wide receivers and tight ends during his two seasons in Atlanta as an offensive assistant, and left to join Shanahan's initial staff with the 49ers. He previously coached collegiately at Elmhurst, Saint Joseph’s and Davidson.
