Keith Urban announced today that he will undergo throat surgery later this month and will have to cancel his upcoming concerts.

A message posted on Keith's Facebook wall says that he has a polyp on his vocal chords. This is not an uncommon occurrence with singers as they are using their vocal chords night after night.

The procedure will be outpatient but will require he be put on complete vocal rest for some time. This means that any of his concerts or appearances that require more than one song will have to be cancelled while any appearances or commitments only needing one song will continue until his surgery. All of his other concerts, including Keith's All For The Hall concert, will have to be rescheduled after he has recuperated.

Good luck Keith, we hope you "fly" through this and feel better soon!
