Though the band did not go into detail, Of Mice & Men took to their social media accounts that due to a medical emergency they would have to cancel 4 of their upcoming shows. In the official statement the band states;

Hey everyone-we’re very sorry to announce that due to a medical situation that requires immediate urgent attention we are being forced to cancel our show tonight and our other shows this week In Grand Junction, Lakewood and Syracuse. We will have more information shortly, but for now we ask for your understanding and patience. We assure you we would not be cancelling anything if it wasn’t 100% necessary. Thank you.

-Aaron, Alan, Phil and Tino

Well, whatever the situation is we will keep you updated as more information becomes available. Till then we wish the band a speedy recovery.
