June 23 [17:00 EDT] -- The fun in the sun at Saturday's Blockbuster Rockfest was tarnished a bit when the day's lone stage diver landed on a security guard and sent him to the hospital.

John Moyer, bass player for the band Soak, leapt into the crowd after his group's set, despite the fact that all Rockfest performers were told not to stage dive. Moyer landed on a security guard, sending him to a local hospital where he was treated and released.

As the security guard was rushed to the hospital, Moyer was escorted out of the arena by police, and was warned that he would be arrested if he tried to return to the grounds. After the incident, the band explained that the accident was the product of too much adrenaline, and that they were glad that the guard was going to be O.K.

Saturday's Rockfest drew a crowd estimated at 150,000, and boasted performances from No Doubt, the Wallflowers, Jewel, Bush, and many others.
