At a time and place approved by the commissioner, the commission members shall administer a weigh-in event in which each contestant must be weighed before the opposing contestant at least eight but not more than thirty-six hours before the match. 2. The weight classes are as identified in the unified rules of mixed martial arts as adopted by the association of boxing commissions and combative sports and in effect on October 1, 2025. 3. The official scales must be available to all contestants a minimum of two hours before the scheduled start time of the weigh-in event.

For a title match, the official scale must be certified and calibrated by a qualified technician. 4. Only contestants approved for the mixed fighting style competition event may be weighed during the weigh-in event. 5. A contestant who has contracted to participate in a specific weight class may not compete if the contestant's weight exceeds the standards for that weight class unless the contract allows the weight differential to be agreed to by the opposing contestant and the opposing contestant agrees to it. 6. If a contestant does not meet the weight requirements during the weigh-in event for the weight class and the opposing contestant does not agree, the contestant or both contestants have two additional hours to make the prescribed weight provided that a weight loss in excess of two pounds [907.18 grams] is not permitted for a contestant weighing less than one hundred forty-five pounds [65.77 kilograms] and a weight loss of three pounds [1360.77 grams] is not permitted for a contestant weighing more than one hundred forty-five pounds [67.77 kilograms]. 7.

If allowed by the promoter and agreed to by the commissioner, the contestants may have an exhibition match.
