Receivers coach Mike Groh has left the Bears after three seasons to join the Los Angeles Rams as passing game coordinator and receivers coach.
Groh arrived in Chicago as part of Marc Trestman's first staff in 2013 and was the only position coach retained by coach John Fox in 2015.
During his time in Chicago, Groh helped receivers Brandon Marshall and Alshon Jeffery record 1,000-yard seasons and reach the Pro Bowl.
When injuries decimated the Bears receiving corps in 2015, Groh helped unheralded wideouts Joshua Bellamy, Marc Mariani, Cameron Meredith and Deonte Thompson step in and contribute.
Assistant strength and conditioning coach Jim Arthur has also left the Bears, rejoining Adam Gase in the same role with the Dolphins. Gase was recently hired as Miami's head coach after one season as Bears offensive coordinator.
