The band announced this weekend that they have flown in a fill-in drummer for the rest of the trek while Ursich returns home to recover from a surgery he was forced to have on an infected cyst.

The band explained the medical situation with the following statement last week, "We are extremely heart broken we are not able to perform for you. Our drummer Nick Ursich had an infected cyst where he sits down to play drums. At first he kept complaining about something near his tailbone.

"Two hospitals in Spain and Switzerland told him nothing was wrong, until we went to a third in Germany and they had to operate on him immediately to remove and drain it out.

"Maintaining the wound has been hard on tour so now he is back in a fourth hospital, where he may stay overnight. More updates to come. To fly across the world and not able to perform hurts us more than anything.

"Please keep Nick Ursich in your prayers! Budapest is offering discounted rates if you keep your ticket for our next show there. We love you so much, and we will be back again in 2016 with a brand new album."

The band later revealed in a series of tweets their plans for completing the tour, "We decided it's best for [Nick] to fly home Monday & get better as he's suffering from multiple set-backs, currently in the hospital."
