UFC Rankings - October 21, 2013

The new UFC rankings have just been released after an action-packed weekend in Houston that saw Cain Velasquez defend his heavyweight title against Junior Dos Santos in a dominant, one-sided TKO victory while Gilbert Melendez and Diego Sanchez managed to put on one of the best fights of the year.
The card was stacked with top fighters and the new rankings are out, but surprisingly there weren't many changes after UFC 166 concluded.
The biggest move happened in the women's bantamweight division where newly minted winner Jessica "Evil" Eye popped into the top ten for the first time debuting at No. 7 overall, but still behind the woman she beat to earn the ranking. Sarah Kaufman dropped down from No. 2 down to No. 5 after losing a close split decision to Eye on Saturday night. The change also bumped up three other women's fighters to take Kaufman's place while three others shifted down after Eye's debut in the rankings.
Following a loss to Daniel Cormier in the co-main event at UFC 166, marking his second defeat in a row, Roy Nelson dropped to No. 10 in the rankings list behind Stipe Miocic, who stood as the other loss the former Ultimate Fighter winner suffered earlier this year at UFC 161. Nelson lost a unanimous decision to Cormier, who remains as the No. 2 ranked heavyweight behind former champion Junior Dos Santos.
Dos Santos lost handily to Velasquez in the main event, but his successful record speaks for itself so despite a loss he holds onto his spot as the No. 1 heavyweight behind the champion.
Gilbert Melendez may have earned a lightweight title shot with his victory over Diego Sanchez at UFC 166, but he remains ranked No. 2 in the division just behind former champion Benson Henderson.
There were no other major changes based on UFC 166, although Jose Aldo did manage to make a move to No. 3 on the pound-for-pound rankings, moving former middleweight king Anderson Silva to No. 4. Matt Brown jumped up one spot in the welterweight rankings to No. 9 with Robbie Lawler bumping down to No. 10, while Antonio Rogerio Nogueira took over the No. 5 slot in the light heavyweight rankings over Lyoto Machida, who will officially become a middleweight this weekend when he faces Mark Munoz in England.
