Post Malone received medical attention after an accidental step caused him to fall through an open trap door onstage during his show Saturday night in St. Louis, Mo. at the Enterprise Center.

Malone had started to sing “Circles” and was stomping down the stage’s ramp when he evidently missed the hole that his instrument had just been lowered into, according to an original report by St. Louis Post-Dispatch. A team of medics appeared on stage to aid his injuries for several minutes as fans lit up with confusion.

Before he stood up to be escorted offstage, the singer addressed fans for the first time and asked them to give him a few minutes, promising that he would be returning. Audiences waited for approximately 15 minutes until Malone slowly walked out, holding onto his ribs.

“St. Louis, I’m so fucking sorry I ruined the show tonight, ladies and gentleman,” he told fans. “I promise next time I come around, I won’t fucking wreck y’all’s night, I’m sorry for that. That being said, fuck… That being said, I want to thank you for your patience and I’m sorry.”

“There was a big-ass hole in the middle of the stage that I busted my ass on,” he continued. “I want to say thank you to everybody for hanging in there and thank you to everybody for… I got the best fucking fans in the world.”

He then went on to perform a slightly shortened set including “Rockstar,” “Sunflower” and “White Iverson” and “Cooped Up,” featuring opener Roddy Ricch.

Malone shared an update on social media on Sunday morning, breaking down his injury during the concert and offering his gratitude to his fans.

“Thank you for the patience. Thank you for putting up with my dumbass,” the rapper said. “Everything’s good, they gave me some pain meds and everything. We can keep kicking ass on the tour. I just want to apologize to everyone in St. Louis and want to say thank you for coming to the show. Next time I’m around this way we’re going to do a two-hour show for you, so we can make up for the couple missed songs.”

Malone also confirmed that he will still be performing in Columbus, Ohio on Sunday night at Nationwide Arena.
