Vitor Belfort has been the face of the UFC in Brazil for well over a decade now. Luke Rockhold has all of the makings of a future UFC superstar stateside. Tonight on FX we will see one of these men take a huge step forward, while the other will be forced to step back and watch. While it may be one of the more unlikely grudge matches that we never asked for; this will be one that could produce Anderson Silva's next challenger. That in itself is a reason to tune in and watch these two former MMA champions as they attempt to earn a shot at dethroning the greatest fight of all-time. It's another UFC moment from a chapter in a book that has yet to be written. It's another one of those can't miss fights that is so closely contested on paper that none of us would put our family or house on it. It goes down just mere moments from now, and it's importance becomes more and more infinite as we anticipate it's final result.
