UFC fighters get tested for various banned substances both in and off competition. Since 2015, the UFC has been cooperating with the biggest anti-doping agency called USADA. This agency handles the testing, analyzes the results and punishes the fighters if they violate the rules.

To be the undisputed champion in the UFC means you are the number one fighter in your weight class. There is only one championship belt in each weight class, and the fighter holding that belt is considered the undisputed champion.

The UFC rankings system is very straightforward. More than 20 media members from various MMA networks vote on the rankings. Their job each week is to vote on the top 15 fighters in each weight class. The UFC then uses their votes to determine fighters' position in the rankings.

The UFC sets up a catchweight fight when both fighters accept the new negotiated weight, discarding the weight limits of their division. Catchweight often occurs when one or both fighters cannot lose enough weight before the weigh-ins, meaning they are heavier than the maximum permitted weight.
