Bono, the frontman of the Irish rock group U2, has written on the band's official website that it is not clear that he will ever play guitar again, following a bicycle accident in New York in November 2013.
The comments were written in his A to Z of 2014 post, which was published on the band's website on New Year's day.
The incident left him with multiple injuries including fractures in his shoulder blade and left elbow - of which he posted an X-Ray - as well as a left eye socket fracture.
The 54-year-old singer was trying to avoid another cyclist when the accident occurred in New York's Central Park.
