When two fighters first met in a fight in front of the public, then contractual fights appeared. There are various reasons to arrange a fake match, but these days this practice has almost disappeared. Since top fighters do not want to lose sponsors, a clear record and championship titles because of a negotiated fight that could derail their entire careers. But when mixed martial arts was in its infancy, when the yakuza controlled promotions, and to attract viewers it was vital to show the victory of the public favorite. In those years, the practice of fake fights was revived. Today we will remember the cases of recognized and proven contractual fights, as well as watch a few dubious fights and together remember how it was.
