Circus officials say the male performer fell from a wheel during an act at the UniverSoul circus Saturday afternoon.
Video shows the performer flying off the so-called 'Wheel of Death', and the crowd started screaming.
Officials say he was fully conscious after the fall.
Mount Vernon firefighters say first responders were already at the scene and helped the injured man right away.
They took him to the hospital and the show continued.
The performer is in stable condition.
