John Mayer has canceled the final week of his European concert tour due to illness, according to a statement posted on his website earlier today.

Though Mayer was able to play a show earlier this week in Copenhagen, he had to cancel his second show in the city.

The statement on his website reads, "After a sold-out performance in Copenhagen, John Mayer was forced to cancel his second show there on 5/31 due to illness. Regrettably, the illness has caused his remaining European shows scheduled through this week to be canceled as well (Amsterdam, Madrid and Manchester)."
