Iggy Pop Stage Dives Into Emergency Room

June 10 [10:00 EDT] -- An attempted stage dive ended with a simple thud and a dislocated shoulder for punk pioneer Iggy Pop last week.

Iggy was working through his headlining set at the R.O.A.R. tour stop in Columbus, Ohio on Friday when he leapt into the crowd and crashed to the floor of the Polaris Amphitheater. Pop was taken to Riverside Hospital, and was released after being treated for a dislocated shoulder.

The injury was the latest hassle in what has been a shaky start for the R.O.A.R. tour, which also features Sponge, the Bloodhound Gang, and the Rev. Horton Heat. Before the tour even got rolling, sponsor Skoal chewing tobacco announced that it would pull its name from all tour promotions after anti-tobacco groups decried R.O.A.R. as an overt attempt to target teens.

Now that the tour is underway, a number of reports have surfaced pointing to sagging ticket sales, and claiming that the tour might be the first casualty of an overcrowded tour season. Despite

reports that the tour is bringing in crowds of as few as 500 people at some locations, tour organizers told "Billboard Online" that the tour will continue as planned.
