Aerosmith [ tickets ] frontman Steven Tyler reportedly was flown to a South Dakota hospital after he fell from the stage during his band's Wednesday (8/6) performance.

According to South Dakota's Rapid City Journal, Tyler was singing "Love in an Elevator" during a concert on the Buffalo Chip Campground main stage in Sturgis, SD, when the sound system cut out. A security supervisor at the campground told the newspaper that Tyler "put his [mic] stand down and twirled around and stepped backwards off the stage," and into the crowd.

Security reportedly rushed into the crowd, which cheered when Tyler got back up. The singer was taken backstage, and Aerosmith guitarist Joe Perry reportedly came out a short time later to tell the audience that Tyler was being taken to the hospital, and that the show--which was at its halfway point when Tyler fell--wouldn't continue.

After a doctor at the concert venue examined Tyler, the singer was flown to Rapid City Regional Hospital.

Injuries and other health problems have racked Aerosmith's members of late. The band postponed several shows earlier this year after Tyler suffered a leg injury, guitarist Brad Whitford sat out the beginning of the current tour leg to recuperate from an unspecified surgery, and bassist Tom Hamilton has missed several shows as he recuperates from what his publicist called "non-invasive surgery." Perry underwent knee surgery earlier this year.

Hamilton underwent radiation treatment for throat cancer in 2006, and Tyler announced he was battling hepatitis C in late 2006.
