Fight Matrix updates the Current MMA Rankings once a week. As the deepest and most inclusive ranking system in the sport, fights all over the globe can have a major impact on the rankings. Let’s take a look at the biggest risers in the divisional rankings. The number in parenthesis is the number of spots that the fighter moved up from the last issued rankings. For the purpose of this article, fighters who were unranked in the previous ranking iteration are excluded.
