Rock band U2 have been forced to cancel a series of TV appearances after lead singer Bono crashed his bike in New York's Central Park.

According to a brief announcement on the band's website, Bono — real name Paul Hewson — injured his arm in a cycling spill in Central Park and will need surgery.

The band had been due to appear on The Tonight Show every day this week, but that's now on hold.

"It looks like we will have to do our Tonight Show residency another time," the band said. "We're sure he'll make a full recovery soon, so we'll be back!"

Bono is reported to be a keen cyclist and earlier this year was snapped riding with his wife Alison Hewson near their French holiday home in Eze-sur-Mer.
