A statement issued by the band's publicist said the remainder of the tour was in doubt, MTV.com said.
"Aerosmith will not perform their Friday, Aug. 7 show at the Canad Inns Stadium in Winnipeg, Manitoba, Canada, based on injuries lead singer Steven Tyler sustained when he fell from the stage at Wednesday's show at Buffalo Chip Campgrounds in Sturgis, S.D.," the statement said. "Additional details will be issued when they are available."
