A dancing stunt knocked down Steve-O.
The reality star was forced to skip Monday's "Dancing With the Stars" after falling on his back during a dress rehearsal earlier in the day.
He landed flat on his back after a failed front flip, smashing his spine into the microphone pack all performers wear. The 34-year-old was already nursing a pinched nerve in his back.
The funnyman didn't break any bones, said dance partner Lacey Schwimmer, but he hasn't yet been cleared to dance on future episodes.
