Fans around the world are reeling after a heartbreaking announcement from the family of Randy Travis, the beloved country music icon whose unmistakable voice and inspirational comeback have touched millions.

At 66 years old, Travis is once again at the center of urgent health concerns, according to a statement released just moments ago from Nashville.

The update, shared by his wife Mary Travis, describes a “serious and unexpected setback” related to his ongoing health battles stemming from the devastating stroke he suffered in 2013.

Though Travis has spent the last decade fighting with determination — relearning to speak, walk, and even sing again — this recent development has left those closest to him “deeply concerned and asking for prayers.”
