U2 lead singer Bono underwent two surgical procedures, with one taking nearly five hours to repair fractures to his face and arm, after suffering from multiple injuries during a cycling accident in New York’s Central Park, Rolling Stone magazine reported Wednesday. The Irish band had announced the accident on Sunday.

A bone in the singer's upper arm was found to be fractured in six places, and required three metal plates and 18 screws to treat the injury. New York-Presbyterian/Weill Cornell Medical Center, where the 54-year-old Bono is being treated, reportedly said that the two surgeries took place on Sunday and Monday. The singer will need intensive and progressive therapy, orthopedic trauma surgeon Dean Lorich, said, according to Rolling Stone.

"He was taken emergently to the operating room for a five-hour surgery Sunday evening where the elbow was washed out and debrided, a nerve trapped in the break was moved and the bone was repaired with three metal plates and 18 screws," Lorich reportedly said, adding that Bono also suffered a "left facial fracture involving the orbit of his eye."

The hospital said, in a statement, that Bono was involved in "a high-energy bicycle accident when he attempted to avoid another rider.” The accident forced the band to postpone its weeklong appearance on Jimmy Fallon's "The Tonight Show." The hospital reportedly said that it was unclear how long Bono would remain under observation before he can be released.

"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," U2 wrote on its website after the accident on Sunday.
