Aerosmith lead singer Steven Tyler toppled like a rag doll Wednesday night in South Dakota -- fallin' down backwards off the stage and comin' up bloody.
Tyler injured his head, neck and shoulder from the spill -- and although he couldn't ruuuun away, ruuuun away from the pain ... he was able to make it to the hospital by helicopter.
UPDATE: Joe Perry's wife Twittered that Steven broke his shoulder and had to get stitches in his head and back.
