I think that Vitor just wants to stay active. He will not risk his position in the MW division by fighting someone like Jacare for example. He knows that he is basically the next No. 1 contender, so he will not risk that.That being said, I don't see how a win over Henderson gives Vitor anything he already doesn't have. He's already made a case for a shot at MW, but one win at LHW isn't enough to get him another shot at 205. I guess maybe if you count anything above 186 at a LHW bout his catchweight wins would count.
However he does not want to be without a fight for many months, so he is going to fight at 205. If he loses, nothing happens. And if he wins, then there are going to be even more talks about how much he deserves a title shot at MW
