Requires a weigh-in to take place the day of a combative sports event

This bill requires all participants in combative sports events (like boxing or MMA) to undergo weigh-ins on the same day as the event, rather than on a separate pre-event date. It directly affects athletes, event promoters, and the regulatory commission overseeing these sports. The key provision mandates the commission to establish rules requiring same-day weigh-ins, replacing any prior timing requirements. This change aims to standardize the process but does not specify additional requirements or penalties.
