U2 may have to postpone their upcoming world tour as Bono recovers from the severe injuries he sustained in a biking accident in New York’s Central Park.

Following the launch of their new album, "Songs of Innocence," the Irish rock stars have been planning a world tour – their first one in three years. The Sunday Independent reports that tour details were to be announced this week, with a June 2015 kick-off in the US looking likely, but the plans being re-evaluated in light of Bono’s accident.

Sources informed the newspaper that Bono will need at least three months to recover from the fractures to his face, left shoulder blade and humerus bone in his upper left arm, which required five hours of surgery in the Emergency Department of Cornell Weill Hospital last Sunday.

According to orthopedic trauma surgeon Dean Lorich, MD, "[Bono] was taken emergently to the operating room...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."

He told Rolling Stone that Bono will "require intensive and progressive therapy," but "a full recovery is expected."

"The injuries will take at least three months to recover. Bono plays guitar a lot, and his arm and shoulder will need extensive physiotherapy if he is going to be ready for the tour. It all depends now on how quickly he can recover," a source told the Irish Independent.

U2’s most recent tour, "U2360," took place in 2011 and grossed $910 million (€736 million). Although that tour centered on big arena and stadium concerts, the venues for their next tour are rumored to be smaller, giving fans the chance to have a more intimate concert experience.
