Rousey's agent, Brad Slater, happens to be the same man who handles Dwayne "The Rock" Johnson and Sly Stallone, and he knows how to make these sort of deals work. He managed to get Rousey cleared for Wrestlemania 31, after all, and don't believe for a second that Dana White didn't know months in advance. With that kind of backing, it's likely Rousey will be cleared for another appearance. There are a lot of reasons to do it, including promoting upcoming Rousey movie projects. While both Slater and the UFC claim that Rousey's deal was for one night, that doesn't mean there won't be a new deal made down the road.
