The band broke the news to fans with the following message on Facebook on Sunday, "Of Mice & Men regrets to announce that the remaining dates of the 'Full Circle Tour' will be cancelled. Therefore, tonight's show at Soma in San Diego and Tuesday's show at El Plaza Condesa in Mexico City will no longer go ahead.

"Lead singer Austin Carlile was admitted to a hospital yesterday morning and per doctor's orders has been kept in overnight for evaluation. The band regrets not being able to perform for their fans and hopes to be back in both cities as soon as possible.

"Refunds for both shows will be available at point of purchase, however Of Mice & Men are planning to reschedule both shows for a later date in the year.

"We will have more news on this in the the coming weeks and tickets holders are welcome to retain their tickets, as they will remain valid for these rescheduled dates."
