Under the revised language, interim titles would still be allowed, but only in specific situations. These include injury or illness to the reigning champion, a refusal or inability to defend the title, or circumstances beyond the boxer’s control, such as travel restrictions.
Supporters of the amendment say the goal is consistency in how championships are defined and recognized. The proposal would limit title designations while maintaining flexibility for inevitable disruptions.
The timing of the change comes as new promotional models enter the sport. Zuffa Boxing is scheduled to launch its first event Friday night on Paramount Plus, with company leadership indicating it intends to operate independently of traditional sanctioning bodies. The bill’s supporters see clearer federal standards as a way to reduce uncertainty during that transition.
The WBO said it already follows similar guidelines. President Gustavo Olivieri said that limiting titles strengthens the status of a full champion and reduces confusion among fighters and fans. He said secondary and interim titles under a full champion can weaken credibility for both the titleholder and the organization.
The WBC said it will review the legislation and comply with any federal rules that are adopted. President Mauricio Sulaiman said the organization respects US law and the authority of local commissions where WBC title fights are held.
Discussion around sanction fees has also attracted attention in recent weeks. Terence Crawford was stripped of his WBC title last month after refusing to pay a sanctioning fee linked to a large purse. Crawford later publicly criticized the fee.
In addition to the championship structure, lawmakers approved several amendments focused on boxer protection. The bill would increase the proposed minimum payment per round from $150 to $200. It would also increase the minimum medical coverage from $25,000 to $50,000 and update timelines for required medical tests, including eye exams, blood work and brain health evaluations.
Amendments introduced by Representative Ilhan Omar would limit boxer contracts to six years, allow fighters to contact other promoters or unified boxing organizations 30 days before a contract expires, and guarantee compensation if a boxer goes six months without being scheduled for a bout.
In a statement after the vote, Representative Brian Jack said the amendments strengthen bipartisan support and move the legislation closer to becoming the first major update to federal boxing law in more than 25 years.
The bill will now be considered by the full House of Representatives.
