Sunday night, between the Lita Ford and Kid Rock concerts, a motorcycle was accidentally driven off the stage at the famed Buffalo Chip campground resulting in four people being injured.

Motorcycle designer and racer Roland Sands drove a bike off the side of the stage and into the crowd. Sands himself was injured in the mishap. Two of the injured spent the night in a local hospital.

A spokeswoman for the Chip, Nyla Griffith, said the accident was a "malfunction."

Kid Rock performed shortly thereafter.
