Justin Timberlake’s “Forget Tomorrow World Tour” has been postponed at the Prudential Center in Newark due to an unspecified injury.

“I’m sorry to postpone tonight’s show. I have an injury that is preventing me from performing,” the singer posted on Instagram.

Timberlake says that he is working to reschedule the concert as soon as possible.

“I promise to make it up to you and give you the show y’all deserve,” Timberlake wrote.

The “Forget Tomorrow World Tour” is in support of Timberlake’s “Everything I Thought I Was” album and began on April 29 in Vancouver.

Timberlake is scheduled to play at the Wells Fargo Center in Philadelphia on Oct. 11. It was unclear if that concert would also be postponed.
