UFC 274 has finally arrived, bringing an outstanding slate of fights—but not without controversy.

Lightweight champion Charles Oliveira was set to defend the belt against top-ranked contender Justin Gaethje, but he failed to make weight. That has led to the title being vacated, and puts the Oliveira-Gaethje matchup in an odd predicament. Gaethje will still win the title if he defeats Oliveira, but the best Oliveira can do with a victory is put himself in position to fight for the belt.
