Who cannot overrule a decision that a wrestler should not participate?

The on-site meet appropriate health-care professional holds a designated role when it comes to the safety and health of the athletes, especially concerning their participation in competition. This individual is tasked with assessing whether a wrestler is fit to compete and has the authority to make that decision based on medical standards. Their assessment is grounded in health-related expertise, ensuring that a wrestler’s well-being is prioritized above competitive factors.

While the coach or the referee might have significant influence over team dynamics and match officiating, respectively, they do not possess the qualifications to make health-related decisions. The opposing team’s coach, similarly, does not have any say regarding an athlete’s health status. Therefore, it is the health-care professional’s responsibility and authority to make the final decision regarding a wrestler's ability to participate, making this option clearly correct in the context of this question.
