In surprising news, drummer Shawn Drover announced today (Nov. 25) that he has quit Megadeth. The stickman had been in the legendary metal band for 10 years.

Megadeth are no strangers to lineup changes, with frontman Dave Mustaine being the only consistent member of the band throughout the group’s existence. Bassist David Ellefson is also an original member, but spent a handful of years out of Megadeth until rejoining the group in 2010.

Drover joined the band in 2004 and played on the band’s last four albums, including 2013′s ‘Super Collider.’ In an official statement [via Blabbermouth], the drummer wrote the following:

After 10 years, I have decided to quit Megadeth to pursue my own musical interests. I want to thank Dave Mustaine and the entire Megadeth family, as well as thanking all the amazing Megadeth fans around the world!!! I truly appreciate all of you. Stay tuned for info on my next musical journey.

There’s no word yet on Drover’s replacement. We’ll keep you posted as more news breaks.
