U2 couldn't make it after Bono's bike accident.

Details have been emerging of just how banged up Bono is after that bicycle accident in New York. He really hurt himself.

So it was clear he wasn't going to be able to show up for U2's week-long residency at The Tonight Show Starring Jimmy Fallon and it has been postponed for the foreseeable future.
