Stone Temple Pilots cancel tour dates due to Scott Weiland vocal chord injury

Stone Temple Pilots have been forced to cancel the last four dates on their summer tour.

The group wrote on their Facebook page that singer Scott Weiland will be unable to perform the shows after suffering a vocal chord injury.

Stone Temple Pilots included a message from Weiland's physician Dr Sid Khosl, who said: "[Wednesday] myself, Dr Eva Van Leer and ENT Dr Keith Casper consulted with Mr Weiland. Upon a video stroboscopy we determined his left vocal chord has likely scarring and his right vocal chord is tremendously inflamed.

"With such a heavy concert schedule and vocal activity we determined that Mr Weiland could potentially run the risk of a vocal hemmorage or suffer permanent damage hence putting him on complete vocal rest."

Tonight's planned concert in Council Bluffs, Iowa and shows from earlier this week will be rescheduled.

Stone Temple Pilots were forced to postpone dates on last year's summer tour after Weiland admitted on-stage that he was battling addiction.
