This past weekend saw the UFC main event debut of Cris Cyborg in her home country of Brazil. While the outcome was no surprise, the fact that Lina Lansberg was able to survive more than a round with the most dominant female fighter on the planet, proved that she belongs in the UFC. With impressive wins throughout the card, many fighters were able to move themselves up the UFC rankings. In fact, six previously unranked fighters now find themselves in the top 15 as a result of last week's action.

Pound-For-Pound

Cyborg's efforts led her to finally appear on the pound-for-pound rankings. She cracked the list at No. 15, and is likely to climb the rankings if she has more performances like she had on Saturday. Because there is no featherweight division for female fighters in the UFC, the P4P ranking is really the only ladder that Cyborg can climb, at this point. Making the list is a huge step for her.

The other movement in the P4P rankings had less to do with last week's fights and more to do with sports writers changing their minds. Rafael Dos Anjos and Luke Rockhold swapped places on the list, with RDA now at No. 12 and Rockhold at No. 13.

Flyweight

In the flyweight division, No. 3 ranked, Jussier Formiga looked strong in his fight against No. 12 ranked Dustin Ortiz. With a unanimous decision win, Formiga cemented himself as one of the top fighters at 125 pounds. Though neither Formiga or Ortiz moved in the rankings, Formiga did break a tie with Kyoji Horiguchi, dropping him to No. 4.

Men's Bantamweight

The men's bantamweight division also had some movement as a result of Fight Night Brasilia. A pair of unranked fighters in Rani Yahya and Michinori Tanaka squared off in the Octagon, and Yahya took the unanimous decision in the close bout. The win moved Yahya into the rankings, sitting at the bottom of the ladder at No. 15.

The only other movement at 135 was between Johnny Eduardo and Takeya Mizugaki. Eduardo, who has won two of his last three, moved to No. 13 and Mizugaki, who has lost three of his last four, fell to No. 14.

Featherweight

Former Bantamweight Champion Renan Barao has found success at 145, winning in impressive fashion against Phillipe Nover. His unanimous decision win in the co-main event propelled him into the featherweight rankings, bringing up the rear at No. 15.

Lightweight

The biggest movement from the weekend came from Francisco Trinaldo, moving from being unranked to No. 13 at 155 pounds. It's about time too, as his win over Paul Felder was his seventh in a row in one of the toughest divisions in the UFC. That streak is the second longest active UFC win streak in the division, behind only Tony Ferguson. This surge, late in his career, could help him make one final push for a belt.

As a result of Trinaldo's climb, some people had to fall. Al Iaquinta and Evan Dunham dropped one spot each to No. 14 and 15, respectively, and Rashid Magomedov dropped out of the rankings completely.

Welterweight

The two welterweight fights this past weekend featured only unranked fighters, so there was no movement as a result of Fight Night. However, positions were swapped at the bottom of the ladder, as Albert Tumenov passed Matt Brown for No. 14. Though Tumenov is coming off a loss, he had won five straight fights before that. Meanwhile, Brown has lost four of his last five, moving this former top five fighter to No. 15.

Middleweight

One of the biggest losers from this weekend had to be Thiago Santos. He was surging in the UFC with four straight wins before losing to Gegard Mousasi at UFC 200. To get a rebound fight, Santos took on Eric Spicely, a fighter on the verge of getting cut by the UFC. However, Spicely upset Santos with a rear naked choke in the first round to save his job. While Spicely didn't enter the rankings, Santos fell out, giving up his No. 15 slot to Krzysztof Jotko.

The only other movement at 185 was not due to the fights this weekend. After it was announced that he would be fighting Rashad Evans at UFC 205, Tim Kennedy moved from No. 13 to No. 12. He swapped places with Dan Henderson, who will be fighting for the belt against Michael Bisping at UFC 204. When people fight for the title, we often see an artificial surge up the rankings, so it is interesting to see Hendo fall a spot.

Heavyweight

The heavyweight division was not shaken up by a fight, but by a potential USADA violation. Ruslan Magomedov was undefeated in the UFC, and had made his way into the top 15. With the division being full of older fighters, Ruslan Magomedov was the new, young talent at 29-years old. However, he has been flagged for a potential violation of the UFC's Anti Doping Policy and was subsequently dropped from the rankings.

This may have hurt him, but it has helped Stefan Struve and Francis Ngannou climb to No. 12 and No. 13, respectively. Daniel Omielanczuk is also in the rankings after a three fight win streak, premiering at No. 14. Omielanczuk will fight Struve on the main card of UFC 204.
