Keith Urban will undergo throat surgery to remove a polyp on his vocal chords, it was announced on his website

"The surgery, an out-patient procedure, while minor, will require complete voice rest followed by an undetermined period of recuperation that will require the postponement of the 'All For The Hall' benefit concert," the statement reads. Urban was set to host the Nashville benefit concert on Jan. 18. He'll honor his commitments leading up to the surgery, the statement adds, and "all other appearances will be rescheduled in the new year."
