The Jonas Brothers were forced to scrap a gig in Zurich, Switzerland on Saturday night after youngest sibling Nick was struck down with a respiratory infection.

The pop trio had made their way to the Swiss city after a fulfilling presenter duties at the MTV Europe Music Awards in Berlin, Germany on Thursday.

However, the band had to let fans down after Nick caught a nasty illness - the first time they have ever canceled a show due to being unwell.

A statement from the group says, "Nick Jonas of the Jonas Brothers is ill with an upper respiratory infection of the nose and throat and the doctor has advised that he not speak or sing. This is the first time that the Jonas Brothers have ever canceled a show for sickness and deeply regret that they will not be able to perform."

The pop sensations promised their fans a full refund.
