The UFC Vegas 20 weigh-in results are in the books following Friday's official tipping of the scales at the Apex in Las Vegas. Heavyweight contenders Jairzinho Rozenstruik and Ciryl Gane square off in the UFC Vegas 20 main event, looking to take the next step toward title contention. Rozenstruik currently sits at No. 4 in the UFC heavyweight rankings, while Gane is ranked No. 7. The winner won't move into an immediate shot at the belt, as champion Stipe Miocic is currently slated to fight Francis Ngannou with the winner expected to defend against Jon Jones. There is also Derrick Lewis, who recently defeated Curtis Blaydes, waiting in the wings.
