U2 frontman Bono says he may never play the guitar again after a bicycle accident that injured his hand, shoulder, elbow and face.

The Irish rocker fell off his bicycle in New York's Central Park in November and underwent hours of intensive surgery to wash out his elbow and repair the bone with three metal plates and 18 screws.

Bono said in a post on his website late Thursday that the accident was more serious than he initially thought.
