Although UFC 157 will be a historic night for mixed martial arts, there's no avoiding the fact that it could also be a death knell for the careers of many female fighters.
Despite the best efforts of Ronda Rousey and the UFC, the women's bantamweight champion's debut is being built on a house of cards.
So far, only a small handful of women have officially been signed to the UFC.
President Dana White, for his part, doesn't seem too committed to women's MMA one way or the other, constantly claiming that he's testing the waters. So, what happens if everything goes south and the event is a total bust?
How could that even happen?
Well, there's more than a few ways Rousey's debut could flame out before it ever heats up. If any of these five circumstances comes to pass, UFC fans might be saying "so long" to Rousey and the women's division before the year is even over.
