An appendectomy is the surgical removal of the appendix and is often performed as an emergency procedure when the patient is suffering from appendicitis. It's unclear at this time when he will be healthy enough to perform again.

Unfortunately for the "Gravity" crooner, this isn’t the first time he's battled a health issue. In 2011, he delayed the release of his album Born and Raised due to a treatment he was receiving for a granuloma discovered on his vocal cords. He underwent a second surgery that August and was put on vocal rest for several months.

Dead & Company is currently next scheduled to perform on Thursday at the Amway Center in Orlando, FL. There is no news yet on the surgery's outcome.
