We now know that U2 frontman Bono’s cycling accident was much more serious than first reported, after Rolling Stone published a list of the singer's painful sounding injuries. The 54 year old was involved in a "high energy bicycle accident in New York's Central Park on Sunday, after he attempted to avoid another rider, according to the magazine.

In a statement from New York-Presbyterian/Weill Cornell Medical Center to Rolling Stone, it is said that Bono was taken to the hospital’s emergency department before undergoing, ”multiple X-rays and CAT scans" followed by five hours of surgery. 

The singer’s left humerus bone in his upper arm was fractured, ‘with the bone shattering in six different places and tearing through his skin’. According to orthopaedic trauma surgeon Dean Lorich, MD, Bono’s elbow was then “washed out and debrided, a nerve trapped in the break was moved and the bone was repaired with three metal plates and 18 screws.”

The singer also suffered "facial fracture involving the orbit of his eye," and three separate fractures of his left shoulder blade. On Monday (November 17th), Bono underwent a further surgery to repair a fractured left pinky finger.

Lorich tells Rolling Stone that while Bono is expected to make a full recovery he will "require intensive and progressive therapy.” It’s not yet clear how long the singer will be recuperating.

"It looks like we will have to do our Tonight Show residency another time - we're one man down," the band said in a statement on their website.

"Bono has injured his arm in a cycling spill in Central Park and requires some surgery to repair it. We're sure he'll make a full recovery soon, so we'll be back! Much thanks to Jimmy Fallon and everyone at the show for their understanding."
