After falling on stage at a concert in St. Louis, the all-clear was initially given. Now the injuries to US star Post Malone seem to be more serious than originally thought. The 27-year-old complains of pain when breathing. He has to cancel the show in Boston.

Post Malone has had to cancel his planned concert in Boston an hour before the start. The reason: The “Circles” interpreter had to be treated in the hospital with breathing problems. “I find it very difficult to breathe and feel a sharp pain whenever I breathe or move,” he wrote in a message on Twitter. He is currently in the hospital and cannot do the evening show. He’s “so damn sorry”. He promises that he will “make amends.” The tickets purchased are valid for the postponement date that he is currently planning.

The news comes just days after Post Malone fell at a concert in St. Louis on Sept. 17. As reported by RTL, the US star was performing his hit “Circles” when the accident happened. He accidentally stepped with one leg into a hole where his guitars were stored under the stage. His upper body then slammed onto the stage with full force. Despite the violent fall, the 27-year-old was able to pull himself up again. After a short treatment by paramedics, he continued the concert despite great pain.

On Twitter he explained in a video how the fall happened. “When we do the acoustic part of the show, we put the guitars on the guitar stand on stage and there was this big hole,” Post Malone said. Usually he just walks around the hole. But he didn’t get the curve. “It hit me pretty bad and it hurt quite a bit,” he explained. However, the hospital provided him with medication for the pain.

During a subsequent examination at the hospital, the doctors found an injury to the ribs. His management confirmed this to CNN. Now the injuries seem to be more serious than originally thought. Post Malone is currently on a major tour of North America, Canada, New Zealand and Australia.
