Last weekend's UFC on Fox 9 event in Sacramento helped a few fighters secure a stranglehold on their spots in their respective divisions. There were a few people that moved up and down a bit as well, but the biggest changes came as a result of something that was announced the day before the event - the indefinite leave of former welterweight champion Georges St-Pierre. Curiously, as soon as GSP dropped the belt and took a leave of absence, he was completely removed from the rankings.
Obviously he's not the champion any more so his place in the welterweight rankings would have been a debate and a half. But he was also removed from the P4P rankings, which is a bit odd since he hasn't retired. I mean, Nick Diaz did say he's retired (technically) but he's still eligible to be ranked. But this change actually ended up pushing Diaz out of the top 10 at welterweight, so I guess there's no cause for concern.
So here's what did happen - GSP's removal from the P4P rankings caused everyone from three to five (Jose Aldo, Anderson Silva, and Cain Velasquez) to move up a spot. Demetrious Johnson moved up two spots to number 5, leaving Renan Barao sitting at six. Eight through ten (Anthony Pettis, Chris Weidman, and Ben Henderson) all moved up one spot. And in perhaps the next most controversial thing in the rankings, Ronda Rousey has made her debut in the P4P rankings at number 10. I don't agree with that at all, but that's an argument I'll make another day.
There were some changes at welterweight as well. Matt Brown moved up one to eight, passing Martin Kampmann. And Tarec Saffiedine is back on the list at number 10, bumping Diaz out.
As a result of UFC on Fox 9, Joseph Benavidez dropped a spot from the number one contender at flyweight to number two after his knockout loss to the champ. John Dodson takes his spot as the top contender for now. Also at 125, Ali Bagautinov jumped two spots to number seven, with Chris Cariaso dropping two down to the nine spot.
At bantamweight, Scott Jorgensen's move down a division saw him drop 3 spots in his old weight class, but somehow people are still ranking him there enough to keep him at 10. Come on rankers, pay attention at least. T.J. Dillashaw, Mike Easton, and Takeya Mizugaki all moved up one spot to compensate.
The only other thing that happened was Mark Hunt moving past Alistair Overeem into the seven spot at heavyweight.
