Section 650-1-1-13 - Amateurs Qualifying as Professionals

Any competitor who wishes to compete as a professional fighter but who has a record of fewer than three sanctioned amateur fights must apply to the Authority for the change to professional status. Factors the Authority may consider include the extent of a fighter's martial arts training, a fighter's experience outside of sanctioned competition, and whether more experienced opponents could potentially pose a risk to a fighter's safety.
