*Usher has been on tour for a while and all has been going pretty smoothly, until Friday night (Dec. 10). He tweeted on Saturday morning some sad news.

“Norfolk – the concert tonight is postponed due to an injury from last night. Pls read more at http://usherworld.com,” Usher tweeted.

The official post said that he had to cancel the performance due to an injury the previous night.

“AEG Live regrets to announce that today’s scheduled appearance by Usher at the Scope Arena in Norfolk, Virginia, has to be postponed due to a physical injury suffered last night in a performance at the Prudential Center in Newark, New Jersey,” representatives from AEG Live announced in a statement. “The attending physician has recommended that Mr. Raymond take the next 2 days to recuperate and heal. The injury is not serious and Mr. Raymond is scheduled to perform Monday night in New York City at the first of two sold-out shows at Madison Square Garden.”
