Rules for the UFC Roster Rankings:
- Fighters can only rank in one weight class
- Fighters who decide to change their weight class will still be ranked in their previous weight class until they have fought at their new weight class
- Since MMA judging is often unreliable, wins and losses will be determined by mmadecisions.com
- Fighters on quasi-retirement will be ineligible
- Suspended fighters are still eligible to be ranked
- Fighters must make their UFC debut before being ranked, however, returning UFC fighters who've been re-signed to the UFC can be ranked immediately
