Justin Timberlake abruptly postponed his concert in Newark, New Jersey, Tuesday night, just over an hour before the show was scheduled to begin.

In a statement shared on the performer’s Instagram page, Timberlake attributed the last-minute decision to an “injury that is preventing me from performing.” He did not share any further details regarding the injury, including when or how he sustained it.

“I’m so disappointed to not see you all – but I’m working to reschedule ASAP. I promise to make it up to you and give you the show y’all deserve,” the post read. “Thank you guys for understanding. Appreciate your support always.”

Timberlake shared the message to his Instagram at 5:45 p.m., just over an hour before the 7 p.m. show was set to begin at the Prudential Center.

Timberlake is next scheduled to perform at the Wells Fargo Center in Philadelphia on Friday. It was not immediately clear whether that show would go on as planned or not.
