While detailing highs and low of 2014 in a long letter published on U2’s website, Bono revealed that he may never play guitar again.

The singer, 54, recalled a bicycle accident he endured in November, which left him with a broken arm, fractured eye socket and shoulder blade.

“Recovery has been more difficult than I thought... As I write this, it is not clear that I will ever play guitar again,” he wrote in a post titled “Little Book of a Big Year: Bono's A to Z of 2014.”

“I personally would very much miss fingering the frets of my green Irish falcon or my (RED) Gretsch. Just for the pleasure, aside from writing tunes. But then does the Edge, or Jimmy Page, or any guitarist you know have a titanium elbow, as I do now? I'm all elbows, I am," he added.

In the letter’s opening, Bono also explained that he faced a similar injury on his 50th birthday, which he called “overcompensation for overindulging on alcohol coming up to the big birthday.”

“I promised myself I would be more mindful of my limits, but just four years on, it happened again - a massive injury I can't blame on anyone but myself, mainly because I blanked out on impact and have no memory of how I ended up in New York Presbyterian with my humerus bone sticking through my leather jacket. Very punk rock as injuries go,” Bono wrote.

As a result of his serious injury, Bono has cancelled public appearances and is concentrating on getting ready for the band’s tour.
