US metalcore outfit Of Mice & Men have cancelled their Australian tour slated for next month as frontman Austin Carlile continues to recover from recent surgeries. 

As revealed last month, the singer has been undergoing treatment for "a rare fibrostic connective tissue disorder called Marfan syndrome" and therefore will not be making the trip Down Under with fellow US band, A Day To Remember. 

Of Mice & Men announced the news in a statement posted to Twitter today. 

"Due to Austin's ongoing recovery from recent surgeries, Of Mice & Men are saddened to announce that they will no longer be able to join A Day To Remember on their Australian tour," the statement reads. 

"The band appreciates your understanding and support of Austin's daily struggle with his chronic illness, and we want our fans to know that he is taking the time and measures needed to recover from his extensive hospital stay."

Following the announcement of Carlile's condition, Of Mice & Men were forced to cancel some European tour dates.

Carlile has been recovering since he was discharged from Stanford University hospital just a few weeks ago. 

Atlanta metalcore group Issues will step in to replace Of Mice & Men on the tour, in what will be their first Aussie shows since supporting The Amity Affliction in 2014.
