Of Mice & Men frontman Austin Carlile has today announced he is leaving the band he founded in 2009 due to ongoing health issues. 

The US outfit were forced to cancel an Australian tour earlier this month while Carlile recovered from surgeries related to a "a rare fibrostic connective tissue disorder called Marfan syndrome" and the singer has revealed his condition has forced the decision to not continue on. 

"My team advised me that if I continued to do so, it would cause 'permanent and irrevocable damage to my spinal cord and nervous system,'" Carlile said in a statement. 

"After learning this I realised that I had to step away from Of Mice & Men. No longer able to scream most of our old material, or continue to scream on anything new, I cannot continue on. 

"This has been the hardest thing that has ever happened in my life for a very long time, but thankfully the band, my family, and closest friends stand behind me and understand."

Carlile confirmed in the post that Of Mice & Men will continue on with the remaining four members.
