According to WDRB, contestants participating in the "Cowboy Pinball" game, stood in the ring and tried to take a one hundred dollar bill from between the horns of a bull.
The first bull was reported to be relatively calm, but the second charged and tossed people into the air.
A witness reported that the second bull did not stop and plowed through the people, doing what bulls do.
Injuries reported included broken ribs, torn ligaments, scrapes, and bruises.
Contestants signed waivers before entering the competition.
