Bono "can't move" for "a couple of months" after sustaining a number of injuries in a bicycle accident.
The U2 front man was left with a fractured face, shoulder blade and broken elbow following the incident in New York's Central Park last month and though his bandmate The Edge insists he is "doing okay", he is ruled out of action for some time.
He said: "He managed to come out of it with what you could only describe as injuries from a car crash, literally, multiple fractures of bones in his elbow and in his back. But he's doing okay.
"We're kind of lucky he was wearing a helmet so he didn't actually break Central Park. But he's made of of tough stuff and he's bouncing back.
"He's been told by his doctors that he's got to stay put. He's back in Dublin right now and basically he can't move for the next couple of months."
