The West Brom legend leaves the Hawthorns to join up with his former team mate and now Blackburn manager Michael Appleton.
Moore was a crowd favourite with the Baggies fans; he did four and a half years at the Midlands outfit before retiring only to return as part of the backroom staff.
Moore will work alongside Appleton and assistant Ashley Westwood as they attempt to revive Rovers’ fortunes.
