What; you mean the Jonas Brothers aren’t invincible?

E! Online reports that the JoBros were forced to cancel a concert on Saturday night in Zurich, Switzerland, after Nick Jonas contracted an upper respiratory infection and was “advised by his doctor not to speak or sing.” 

In an apology to their fans on their Twitter page, the Lines, Vines and Trying Times trio note that this is the first time that they have ever canceled a concert due to illness. (Bailing on a show due to fear of illness is another story.)

Fear not, though; Nick is on the mend, and the band will be resuming their tour in Spain on Tuesday. The singer notes on the group’s Twitter page on Sunday,

“I am happy to tell everyone that I woke up this morning, and I’m already feeling better! Thanks for all the prayers. Can’t wait to rock Bilbao!”

Best wishes for a full and speedy recovery, good sir.
