Welterweight upsets were the story at UFC Fight Night 29.
In the main event, Jake Shields out-grappled jiu-jitsu ace Demian Maia for five rounds. The loss was Maia's first since moving to 170 pounds. Shields, meanwhile, finds himself back in title contention two-and-a-half years after losing to Georges St-Pierre at UFC 129.
The co-main event saw Dong Hyun Kim stun Erick Silva with a left hand while weathering a tremendous storm from the Brazilian.
Also, in his debut fight in the welterweight division, Rousimar Palhares became the first fighter to submit Mike Pierce. However, because he held on to his heel hook too long, Palhares was later released from the UFC roster due to repeated unsportsmanlike conduct.
How did the outcomes of these noteworthy welterweight bouts impact the 170-pound ladder?
With UFC Fight Night 29 in the books and UFC 166 ahead, here are the latest official UFC rankings.
No top pound-for-pound fighters competed at UFC Fight Night 29, but one small change was made to the rankings.
As his rematch with Chris Weidman draws near, former middleweight champion Anderson Silva moved ahead of featherweight titleholder Jose Aldo. The Brazilian greats have been flip-flopping positions regularly since Silva was dethroned in July.
At UFC 166, Cain Velasquez will try to close the distance between himself and those two men. The heavyweight champion will complete his trilogy with Junior dos Santos on the fight card.

The heavyweight division was on break for UFC Fight Night 29.
As a result, no adjustments were made in the division's rankings.
However, the class will heat back up at UFC 166, where champion Cain Velasquez will try to retain his belt against rival Junior dos Santos. Additionally, Daniel Cormier and a shrinking Roy Nelson will battle in what could be their final fight in the heavyweight division.
A bout between Gabriel Gonzaga and Shawn Jordan will also be included on the UFC 166 main card.

It wasn't the best showcase of light heavyweight talent, but UFC Fight Night 29 did feature two 205-pound bouts.
An overweight Thiago Silva bested a fading Matt Hamill via decision, and Fabio Maldonado squeaked by with a controversial decision victory of his own against Joey Beltran. While Silva has a decent resume on paper, he'll need a much more impressive win than the one he earned on Wednesday in order to crack into the Top 10. Maldonado, meanwhile, is still working his way out of the division's basement.
No light heavyweight fights will be contested at UFC 166, but a battle between Dan Henderson and Vitor Belfort is now less than one month away.

Although no middleweights fought at UFC Fight Night 29, the division's rankings were altered significantly following news that the UFC released Yushin Okami.
Previously ranked No. 6 in the 185-pound class, Okami's removal from the UFC rankings made room for Tim Boetsch who also surpassed Chael Sonnen on the middleweight ladder. Sonnen has not fought at 185 pounds since July 2012 and is next expected to compete at light heavyweight again.
Boetsch will try to prove he is worthy of his Top 10 position at UFC 166 where he'll meet replacement opponent CB Dolloway. Originally, Boetsch was booked to meet Luke Rockhold on the fight card.

UFC Fight Night 29 was a huge event for the welterweight division.
Jake Shields out-grappled Demian Maia to return to title contention. Despite beating the Brazilian, though, Shields sits three spots below Maia in the latest middleweight rankings.
With Shields' addition to the Top 10, former Strikeforce champion Tarec Saffiedine was bounced from the rankings, as he has still not made his UFC debut.
Dong Hyun Kim and Rousimar Palhares both picked up wins at UFC Fight Night 29 that likely put them near the Top 10. However, Kim will need at least one more victory before being considered an elite 170-pounder, while Palhares' hopes of becoming a Top 10 UFC welterweight were squashed by his release from the organization.
At UFC 166, Nate Marquardt and debuting welterweight Hector Lombard will try to take a step closer to 170-pound title contention. The former UFC middleweights are two of the biggest names not currently ranked in the welterweight division.

The only lightweight bout contested at UFC Fight Night 29 featured a pair of UFC newcomers.
Alan Patrick impressed in that matchup with Garett Whiteley. However, with only one UFC win, Patrick obviously has a lot of work ahead of him before he's mentioned among the best 155-pound fighters in the world.
Gilbert Melendez is one of those elite lightweights, and he'll try to maintain that standing against Diego Sanchez at UFC 166. A bout between struggling lightweight notables George Sotiropoulos and KJ Noons is also expected.

No 145-pounders were seen at UFC Fight Night 29.
Accordingly, no changes were made to the featherweight rankings this time around.
It's unlikely any adjustments will be made following UFC 166. The only 145-pound bout on that fight card includes low-ranked Jeremy Larsen and UFC newcomer Andre Fili.

Despite losing at UFC Fight Night 29, TJ Dillashaw's stock rose in the bantamweight division.
Judges saw Dillashaw as the loser of his bout with Raphael Assuncao. However, the controversial decision was enough for the rankings panel to move Dillashaw ahead of Mike Easton, who lost more decisively to Assuncao in December 2012.
Although all didn't agree he was the deserving winner on Wednesday, Assuncao also moved upward in the 135-pound rankings.
UFC 166 will also only feature one bantamweight matchup. It is one of much less significance as Dustin Pague meets Kyoji Horiguchi.

The flyweight division was back in action at UFC Fight Night 29, but a bout between Chris Cariaso and Iliarde Santos did not result in any changes to the class' rankings.
Instead, Cariaso held his position in the Top 10 and on the UFC roster by beating Santos, who has lost his first three bouts inside the Octagon. After avoiding a third straight loss of his own, Cariaso can now turn his focus back toward contending for a championship.
At UFC 166, John Dodson will welcome Darrell Montague to the Octagon. Having only lost to Ian McCall in his past 11 fights, Montague is not your average UFC newcomer and should be added to the Top 10 soon after his bout with Dodson.

While several ladies battle for UFC roster spots on TUF 18, the women's bantamweight division has been on hiatus.
Finally, females will return to action at UFC 166, though. Former Strikeforce champion Sarah Kaufman will make her UFC debut against Bellator veteran and fellow UFC newcomer Jessica Eye.
Kaufman is already highly ranked in the women's bantamweight division, but Eye will have a good chance to prove her worth to UFC fans at UFC 166. The 27-year-old has only lost once in 11 career bouts and is not far removed from a win over former Bellator champion Zoila Gurgel.
