5-0. Why not? No one else to fight, Okami will get his shot if he wins. This is probably just a refresher fight. Why have him come back from injury to fight Silva right away? That would make less sense than Leites fighting Silva, which imo is still reasonable. Of course you aren't going to get the greatest hype for a fight when Silva has pretty much wiped out the division. Why not give it to up and comers with a decent win streak going for them. He is the only one who has a decent one other than Maia and based on their amount of wins, I guess they felt it more deserving.
