Tyler, 63, was taken to Paraguay's La Costa medical center after suffering cuts to his face and the loss of two of his teeth after the fall.
"Mr. Tyler had a small accident that prevents him from staging the concert tonight," a spokesman for the concert organizers told reporters. "He is fine, he's in his hotel, but he's not able to do the concert."
Another organizer stated that Tyler had been suffering from dehydration and gastrointestinal problems. The concert has been rescheduled for Wednesday.
