UFC Rankings Shake-Up After UFC Fight Night: Rosas Jr. vs. Barcelos

The September 29 rankings update covers a full week of activity. Saturday's UFC Fight Night in Las Vegas provided the live backdrop — Raul Rosas Jr. headlined for the first time and delivered — but the bigger ranking story played out away from the cage: Tom Aspinall vacated the heavyweight title, and the ripple effects reshuffled two divisions and the pound-for-pound list in one update.

Biggest Movers

Fighter	Division	Old Rank	New Rank	Change
Joshua Van	Pound-for-Pound	#11	#6	+5
Joanderson Brito	Featherweight	#15	#11	+4
Alonzo Menifield	Light Heavyweight	#13	#11	+2
Alexander Volkov	Heavyweight	#2	#4	-2
Tom Aspinall	Pound-for-Pound	#6	#8	-2
Leon Edwards	Welterweight	#8	#10	-2
Manel Kape	Flyweight	#2	#1	+1
Ciryl Gane	Heavyweight	Contender #1	Champion	—

Main Event: Rosas Jr. Stops Barcelos in Five

Raul Rosas Jr. needed five rounds but got the finish. Barcelos passed out after a takedown against the cage in the fifth, and referee Herb Dean stopped it immediately. Barcelos was taken to hospital as a precaution. Rosas Jr. extended his win streak to six in a row and claimed his first UFC main event headliner.

Neither fighter moves in the bantamweight rankings this week. Barcelos stays at No. 8, Rosas Jr. remains outside the top 15. The performance makes a strong case for entry, and the committee may act on it in the next cycle.

Heavyweight Title: Gane Takes Over

Tom Aspinall vacated the undisputed UFC heavyweight title after an eye injury that required two surgeries earlier in 2026. Post-operative complications and a re-injury made a return timeline impossible to set. Aspinall drops from champion to No. 1 contender and slides two spots to No. 8 on the pound-for-pound list.

Ciryl Gane moves into the champion slot. He earned the interim title in June by stopping Alex Pereira in the second round, and that interim reign is now recognized as the full title pending a defense. Aspinall remains the mandatory challenger, but no date has been confirmed.

The heavyweight rankings reshuffle around the vacancy: Alexander Volkov drops from No. 2 to No. 4, while Sergei Pavlovich rises to No. 2 and Alex Pereira climbs to No. 3.

Joshua Van Jumps Five Spots in P4P

The flyweight champion gets the recognition his title win over Alexandre Pantoja deserved. Van's dominant performance at UFC 331 last week was enough to move the committee, and he jumps from No. 11 to No. 6 on the pound-for-pound list — one of the bigger single-week P4P climbs in recent memory.

Pantoja falls one spot to No. 2 in the flyweight division, with Manel Kape now holding the No. 1 contender position after his own strong run of form. Justin Gaethje gains one spot to No. 3 in the updated P4P list.

Joanderson Brito Bursts Into Featherweight Top 11

Brito's knockout over Giga Chikadze at UFC 331 earns him a four-spot jump in featherweight, from No. 15 to No. 11. The quality of the finish pushed the committee to act immediately rather than wait. Melquizael Costa, Steve Garcia, Aaron Pico, and Jamall Emmers each drop one position to accommodate the move.

Ailín Pérez Over Norma Dumont

One of the cleaner stories from the Las Vegas card. Pérez defeated Dumont by unanimous decision in women's bantamweight. There was a post-fight confrontation that required security to intervene twice, but on the scorecards Pérez was clear. The official women's rankings have not yet adjusted — Dumont holds at No. 2 and Pérez at No. 4 — expect that to change in next week's update.

Welterweight and Light Heavyweight Notes

Leon Edwards continues to drift down the welterweight rankings, falling two places from No. 8 to No. 10. Joaquin Buckley moves to No. 8 and Uroš Medić to No. 9 in the reshuffle. In light heavyweight, Alonzo Menifield gains two spots to reach No. 11, a reflection of consistent activity in a division where the top remains locked behind champion Carlos Ulberg.
