This fight is set for UFC 235 on March 2nd at the T-mobile arena in Las Vegas.
It will be for the Light-Heavy weight championship of the world.
Jones (23-1-0) has regained the title in his last fight, one of the most anticipated rematches in MMA history against the tough competitor Alexander Gustafsson (#2 ranked light heavyweight).
Smith (31-13-0) is coming off a really impressive three wins Streak against three experienced fighters (Rashad Evans, Mauricio Rua and Volkan Oezdemir) the last named being his most recent win (3 months ago) by submission inside the 3rd round.
Smith is the Underdog for this fight, but he has claimed that is not concerned about that fact and he has nothing to lose. A win over Jones would be considered as the biggest upset in the history of MMA history.
