After falling through the stage,

Post Malone apologises to the audience

After taking an unintentional step onstage during his performance

at the Enterprise Center in St. Louis, Missouri, on Saturday night

Post Malone needed medical assistance after falling through an open trap door.

Malone appeared to miss the hole that his instrument had just been dropped 

into as he was beginning to sing "Circles" and stomping down the stage's ramp

 Fans erupted in astonishment as a team of doctors 

entered the stage to treat his wounds for several minutes.
