Post Malone was crushing his show in Saint Louis this weekend when (he says) he forgot that there was open part to the stage for other instruments, and he fell through it while performing.

The fall ended up breaking 3 ribs, and put an end to his show.

Post came back on stage after a 10-minute break and apologized to STL saying he’d make it up to them.

Check out a different angle of the fall – it looks painful!
