The latest MMAWeekly World MMA Rankings were released on Sunday, May 31. This system ranks the Top 10 MMA fighters from all across the world in each of the seven most widely accepted weight classes.

Taken into consideration are a fighter's performance in addition to his win-loss record, head-to-head and common opponents, difficulty of opponents, and numerous other factors in what is the most comprehensive rankings system in the sport.

Fighters who are currently serving drug-related suspensions are not eligible for Top 10 consideration until they have fought one time after the completion of their suspension.

Fighters must also have competed within the past 12 months in order to be eligible for Top 10 consideration.
