The post went on to say it's unclear if the 72-year-old singer will be healthy enough to attend the GRAMMY Awards on Monday, where he is nominated for his 15th GRAMMY for his album "My Dream Duets," released in October 2014.

It is unknown why the singer had to undergo the emergency oral surgery that led to his subsequent hospitalization.
