UFC Rankings Explained
The UFC rankings are determined by a voting panel comprising members of the MMA media. These media members are tasked with voting for the top fighters in the UFC, categorized by weight class and pound-for-pound rankings. To be eligible for voting, a fighter must be in active status within the UFC. A fighter can hold rankings in multiple weight divisions simultaneously if they have competed in those divisions.
It's important to note that the champion and interim champion of each division are automatically considered to be in the top positions and are therefore not eligible for voting by weight class.
