Final answer:
A cowboy may be disqualified in Bareback Riding for violations like touching the horse or themselves, being bucked off too early, mistreating the horse, or using illegal equipment.
Step-by-step explanation:
A cowboy might be disqualified in Bareback Riding for a number of rule violations. The bareback riding event in a rodeo requires a cowboy to ride a bucking horse without a saddle, using only a rigging to hold onto. If a cowboy fails to do so properly, such as by touching the horse or themselves with their free hand, or if they are bucked off before the required time, they may face disqualification. Additionally, mistreatment of the horse or use of illegal equipment can also result in disqualification, as can failing to adhere to the competition's specific rules and standards for fair play and safety.
