Frank Ocean has been forced to cancel the three remaining dates of his Australian tour due to a small tear in one of his vocal cords. 

The R&B singer kicked off the mini-tour on Thursday night at Melbourne's Festival Hall. The sold-out show dates coincided with his scheduled appearance at the music festival Splendour in the Grass.

“After last night’s concert in Melbourne at Festival Hall, it was necessary to seek medical advice due to vocal issues Frank Ocean experienced during the show,” Live Nation said in a Facebook post.  "It has subsequently been confirmed that Frank has suffered a small tear to one of his vocal cords and has received medical advice that he must rest his voice."

In addition to Friday night's cancellation, the shows scheduled for July 29 and July 30 have been canceled and won't be rescheduled, Live Nation said.

Billboard reports that during a performance of "Forrest Gump" on Thursday night, the singer told the crowd, “I’m sick … I don’t know if you care.”

He also offered his gratitude to the crowd after closing out the show with an encore. 

“I don’t wanna speak much tonight but I do wanna thank you guys,” he said.
