The band's Facebook page was also updated on Monday to an illustrated image, notably scrubbing Buckingham's image from its profile (although band images including Buckingham still remain on the page).
Buckingham joined Fleetwood Mac in 1975 when he and his then-girlfriend Stevie Nicks -- who had been playing as a duo -- were recruited by Mick Fleetwood and the rest of the group. He played with the band until 1987 and then returned in 1997. Fleetwood Mac was inducted into the Rock and Roll Hall of Fame in 1998.
Over the years, Buckingham released six solo albums and last year duetted with Christine McVie of Fleetwood Mac on Lindsey Buckingham Christine McVie, which also featured the band's Mick Fleetwood and John McVie.
