Symone Black did a beautiful job singing "(Sittin On') the Dock of the Bay" by Otis Redding, but it's what happened after her performance that left the judges stunned.
As she was talking to Randy Jackson, the 16-year-old stumbled, lost her balance, fell off stage and hit her head.
Steven Tyler belted out in horror:
"F-k man! She hit her head!"
Executive producer of the show, Nigel Lythgoe, and a medic rushed to help Symone.
The fall is going to be further addressed on Thursday's episode of AI.
