After a hard-fought submission win at Saturday’s UFC 159 event, veteran Pat Healy was the big mover in this week’s USA TODAY Sports and MMAjunkie.com MMA fighter rankings. He moved up from No. 15 and supplanted Jim Miller in the No. 8 slot at lightweight.
Heavyweights Roy Nelson and Mark Hunt also moved up to a spot due to UFC 159, though other event participants held steady despite their performances.
The rankings are unlikely to see much movement over the next few weeks as the UFC goes into a three-week break before its next show, UFC on FX 8, on May 18.
The rankings take into account a fighter's wins/losses, quality of competition, finishing rate/dominance and frequency of fights.
Fighters are no longer eligible to be ranked after they've been inactive for 24 months, either due to injuries, drug/conduct suspensions, contract disputes or self-imposed hiatuses.
Fighters serving drug/conduct suspensions are eligible to be ranked, so long as they're not inactive for more than 24 months.
To the best of our ability, fighters will be ranked in their primary weight class. Catchweight fights and bouts outside the fighter's primary weight class can have a positive or negative impact on the ranking. However, fighters can be ranked in only one weight class at a given time, and in most cases, they won't be ranked in a new weight class until they've had their first fight at that weight.
