Update: Osiris Maia, member of the Brazilian Mixed Martial Arts Confederation, the entity responsible for regulating the Shooto Brazil events, is not sure if they will allow the male vs. female fight to happen.
"There’s nothing in the rules that specific prohibits a man to fight a woman, but when you interpret the rules you know that both athletes must be in the same level, so there’s no way a man should be allowed to fight a woman," Maia told MMAFighting.com.
"We haven’t received the official card yet from the promotion, we’ll get that (on Thursday) at the weigh-ins," he continued. "I wasn’t informed about that yet. They announced it to the media only, but if you ask me if we’re allowing it to happen, I don’t think so. I think it’s a disparity. We’ll see what’s going on tomorrow at the weigh-ins."
