Timberlake cancelled his Oct. 8 Forget Tomorrow World Tour an hour before showtime due to a mysterious injury. “I’m so sorry to postpone tonight’s show,” said Timberlake via an Instagram post. “I have an injury that is preventing me from performing. I’m so disappointed to not see you all — but I’m working to reschedule ASAP.”

Prudential Center officials are working to provide more information to would-be concertgoers after Justin Timberlake abruptly postponed his show.
