The Aerosmith singer, 61, reportedly suffered minor head and neck injuries and a shoulder injury, though the seriousness of his condition is not yet clear.
It is being said that Tyler fell off the stage as the band was performing "Love In an Elevator" and was then assisted backstage before being rushed to the Rapid City regional Hospital.
Mike Sanborn, spokesman for the Buffalo Chip Campground, which hosted the outdoor concert, tells the Associated Press about the incident: "He was good-natured about it. He was in good spirits when he got in the helicopter. He was talking and joking with the physician."
According to the band's rep, Aerosmith's show on Friday Winnipeg, Canada, has been canceled as Tyler recovers.
Last year, Tyler returned to rehab in order to address a dependency on pain and sleep medication.
