U2 lead singer Bono will be forced to undergo surgery on his arm after a cycling accident in New York City's Central Park.

The injury was announced in a brief statement from the other members on the band's official website late Sunday. The statement did not reveal when or how Bono -- real name Paul Hewson -- suffered his injury. 

Guitarist The Edge, bassist Adam Clayton, and drummer Larry Mullen also said that they would have to rescheduled their scheduled weeklong appearance on NBC's "Tonight Show" because they were "one man down."

"We're sure he'll make a full recovery soon, so we'll be back!" the statement concluded. "Much thanks to ["Tonight Show" host] Jimmy Fallon and everyone at the show for their understanding."

An NBC spokesman confirmed to the Associated Press that the Irish rockers had pulled out of their booking due to the accident. 

The accident was revealed four days after the rear hatch on Bono's private jet came off while landing in Berlin. 

Berlin airport spokesman Ralf Kunkel told the Associated Press he was not sure how the hatch came off and that German authorities were investigating the matter. He also said the aircraft was never in danger of crashing.
