John Mayer Goes On 'Indefinite Hiatus': Singer's Vocal Cord Injury Forces Him To Cancel Tour

John Mayer announced he's canceling his upcoming tour because of a vocal cord injury.

USA Today reports Mayer broke the news on his blog. He had a granuloma on his vocal cord last fall and it's grown back.

From Mayer's blog:

This is bad news. Because of this, I have no choice but to take an indefinite break from live performing. Though there will be a day when all of this will be behind me, it will sideline me for a longer period of time than I care to have you count down.

Mayer goes on to explain, "a granuloma forms and continues to snowball because it’s in a spot where the vocal cords hit together and there’s no way to really give it a chance to heal without a good stretch of time and some pretty intensive treatment."

Earlier this month, the "Your Body is a Wonderland" singer announced a release date for his forthcoming album, Born and Raised. It will come out on May 22 and the first single, "Shadow Days," is available now on iTunes.
