Wallen's voice was "shot", and he was forced to cancel a gig.
Morgan Wallen was forced to abruptly cancel a gig in Oxford, Mississippi, at the last minute, Country Now reports.
Using Instagram Stories, the Thought You Should Know singer explained that his voice was “shot” and the show wouldn’t go ahead.
“After last night’s show I started losing my voice so I spent the day resting up, talking to my doctor and working through my vocal exercises trying to get better.
"I really thought I’d be able to take the stage and it kills me to deliver this so close to showtime, but my voice is shot and I am unable to sing,” Wallen wrote in his Stories.
He continued, “All tickets will be refunded at point of purchase. I am so sorry, I promise you guys I tried everything I could.”

While Wallen, the headliner, couldn’t perform his set, support acts HARDY, Ernest & Nate Smith performed their sets at Vaught-Hemingway Stadium.
After debuting at #4 upon release (3 March) and spending three weeks in the ARIA Albums Chart, Wallen’s new album, One Thing At A Time, made it to #1 last month, just in time for his Australian tour.
Wallen’s monolith new 36-track album features collaborations with Eric Church (Man Made A Bar), HARDY (In the Bible), and Ernest (Cowgirls).
To celebrate his new album, Wallen recently returned to his former high school in Knoxville, Tennessee.
Lucky students, faculty members and locals gathered on the school’s baseball field and enjoyed a surprised and unannounced pop-up concert from Wallen, which featured several songs from his new album and many of his country radio hits, such as Thought You Should Know, You Proof and More Than My Hometown.
The popular country music singer recently won the Country Music Artist Of The Year award at the iHeartRadio Music Awards.
Accepting his award via video message while on his One Night At A Time tour in Australia, he said, “I just wanted to say thank you to my fans first and foremost for making this possible. You guys blow my mind every day.
"Thank you to iHeart for playing my music. Thank you to everyone who stays and continues to be in my corner. I really appreciate it. Thank you for making me the iHeart Country Artist Of The Year, it’s an honour and a privilege.”
