On Saturday night, the UFC had its largest event in company history.
The fight was in the making for two years, during which time both Silva and Sonnen won two fights since their first encounter at UFC 117.
Anderson Silva came out the victor and won by second-round TKO after hitting Sonnen with a devastating knee that started it all off.
Silva remains the No. 1 pound-for-pound fighter, but what about Sonnen?
Take a look.
First up is Vitor "The Phenom" Belfort. Belfort is 7-1 in his last eight fights, with the only loss coming at the hands—technically, foot—of Anderson Silva.
Those fights were contested at several different weight classes, ranging from 205 lbs to 185lbs, with several stops in between.
Belfort was forced to pull out of a fight against Wanderlei Silva due to a broken hand, and his next fight has yet to be announced.
Chad Mendes was a big winner on Saturday night, as he earned a TKO victory over Cody McKenzie just seconds into the first round.
Mendes has officially rebounded from his loss to Jose Aldo at UFC 142, and he put himself in line to earn another title fight or at least a top contender fight.
Ian McCall is almost universally considered the No. 3 flyweight in the world, behind both Demetrious Johnson and Joseph Benavidez.
The UFC flyweight division is still relatively small, but perhaps a fight with the other loser in the mini-tournament, Yasuhiro Urushitani, is in the cards for McCall.
Martin Kampmann has proven to be a threat in the welterweight division as of late.
His last two victories have been come-from-behind wins against both Thiago Alves and Jake Ellenberger, the first ending in a third-round submission and the second in a Round 2 TKO.
Kampmann's next fight is rumored to be against Johny Hendricks, for a No. 1 contender spot against the winner of Georges St-Pierre vs. Carlos Condit.
Renan Barao is easily the hottest young prospect in MMA today. He has an outstanding record and scored a clear unanimous decision over the former title challenger, Scott Jorgensen.
Barao will now face Urijah Faber for the interim bantamweight championship at UFC 149.
In Nate Diaz's last fight, he was able to do something that no fighter before him had done: finish Jim Miller.
Miller has lost four times in his career, to Frankie Edgar, Gray Maynard, Benson Henderson and Diaz. Diaz was the only one to finish him.
With three straight wins since returning to the lightweight division, Diaz earned the right to await the winner of the upcoming Frankie Edgar-Benson Henderson rematch.
Johny Hendricks has been the biggest mover in the welterweight division in the last 12 months, scoring two huge victories over former title challengers Jon Fitch and Josh Koscheck.
He knocked out Fitch in just 12 seconds and earned a split decision over Koscheck.
Hendricks was hoping to get a crack at the winner of Carlos Condit and Georges St-Pierre, but he will instead face Martin Kampmann for a No. 1 contender spot.
The former WEC featherweight champion is up next, as Urijah Faber checks in at No. 18 on our list.
Faber has contended for the UFC bantamweight title and lost to Dominick Cruz at UFC 132. At UFC 149, he will face Renan Barao for the interim bantamweight title.
He has wins over several top-10 fighters and is, without a doubt, one of the best fighters in the world today.
Mauricio Rua remains in the top 25, as he is still a top-five light heavyweight.
Shogun was last seen at UFC 139, where he had arguably the greatest fight in MMA history against Dan Henderson. Shogun lost a unanimous decision in that bout.
He will return in the main event of UFC on Fox 4 against Brandon Vera.
Chael Sonnen came into the fight on Saturday night with everything to prove. He had a chance to dethrone the greatest fighter of all time and back up all of his trash talk.
For the first five minutes he did just that, as he took down and controlled Anderson Silva.
Then, in the second round, Silva did what he does best, as he used his pinpoint striking to finish Sonnen by TKO.
However, Sonnen remains the No. 2 middleweight in the division and a top-25 pound-for-pound fighter.
The former lightweight title challenger, Gray Maynard, is almost universally considered to be a top-three lightweight in the world.
Maynard was last seen in action at UFC on FX 4, where he earned a unanimous decision over Clay Guida in a fight that saw Maynard, and not Guida, be the fan favorite.
Maynard will likely fight a top contender next.
Cain Velasquez is the former UFC heavyweight champion, and he is on a mission to reclaim the belt from Junior dos Santos.
If Velasquez's last fight against Antonio Silva is any indication, there may be no stopping Velasquez. He took Silva down in mere seconds and TKO'd him in the first round.
Junior had better make sure his takedown defense is as good as ever for the rematch.
Demetrious Johnson is a one-time bantamweight title challenger and soon-to-be flyweight title challenger.
After earning a unanimous decision over Ian McCall, Johnson put himself in the finals of the tournament to crown the UFC's first ever flyweight champion.
"Mighty Mouse" will face Joseph Benavidez at some point in the future.
Joseph Benavidez is considered by many to be the uncrowned flyweight champion of the world. With the close fights that Demetrious Johnson had with Ian McCall, many think that Johnson will not be able to compete with Benavidez.
In Benavidez's career he has only lost twice, and both of those came at the hands of the bantamweight champion, Dominick Cruz.
Benavidez will look to finally get a belt by beating Johnson at a date to be announced.
Rashad Evans fell short in his title-reclaiming effort against Jon Jones, but he'll certainly be back to fight for the title again.
In the meantime, Evans is stuck in a Jon Fitch (pre-Johny Hendricks) type of situation, where he is one of the best fighters in the division, but may have nothing to offer the champion.
Carlos Condit is the interim UFC welterweight champion, and he won the title back in February when he defeated Nick Diaz by close unanimous decision.
Condit then elected to sit out and wait for Georges St-Pierre to recover, and a title unification fight is scheduled for UFC 154.
Dan Henderson just gets better with age.
At 41 years old, Henderson is as good as ever and will be fighting for a UFC title for the third time in September.
Henderson has won six of his last seven fights, including knockouts at middleweight, light heavyweight and heavyweight. That's pretty impressive.
As a former lightweight champion and a man fighting at least one weight class higher than he possibly could, Frankie Edgar belongs this high on the pound-for-pound list.
After UFC 150, Edgar will have fought the same three opponents in his last six fights. Win or lose, I'm sure he'll be looking for new opportunity.
Perhaps the featherweight division is calling him.
The UFC's most recent official champion is also the lowest ranked of all the champions.
Benson Henderson won the lightweight title when he defeated Frankie Edgar by unanimous decision at UFC 144 in Japan.
Now Henderson will have a rematch with Edgar as the main event of UFC 150.
At UFC 146, Junior dos Santos scored a TKO victory over Frank Mir, just as everyone assumed that he would.
Earlier, on the same card, Cain Velasquez earned a No. 1 contender spot when he defeated Antonio Silva.
Dos Santos and Velasquez are now rumored to have a rematch at UFC 152.
"The Dominator" is yet another fighter who was forced out of a fight due to injury. Dominick Cruz was set to face Urijah Faber for a third time in the co-main event of UFC 148, but a torn ACL forced him from the fight.
When he returns, he will likely face the winner of the upcoming Faber-Renan Barao fight, which will take place as the main event of UFC 149.
Jose Aldo remains in the No. 4 spot in the pound-for-pound rankings. Aldo has decimated his competition at 145 pounds and was set to face Erik Koch at UFC 149, but an injury forced him from the card.
His next fight will likely be against Koch, but nothing is set in stone and his opponent could easily change.
Georges St-Pierre has finally dropped from the No. 2 spot in the pound-for-pound rankings.
Some will be happy to see this change, and others will be absolutely livid. There are arguments for both sides, but the panel of writers has spoken, and St-Pierre is now No. 3.
He will return to face Carlos Condit to unify the titles at UFC 154.
It has finally happened: Georges St-Pierre is no longer one of the top two pound-for-pound fighters on the planet.
Inactivity has ruined St-Pierre's momentum, as Jones has defeated three top contenders since St-Pierre's last fight.
Jones will look to make it four top contenders when he faces Dan Henderson at UFC 151.
Talk about a shocker, right?
Anderson Silva remains entrenched as the No. 1 pound-for-pound fighter on the planet, with 15 straight victories in the UFC, 10 title defenses and 13 finishes during that time.
On Saturday, Silva defeated Chael Sonnen by second-round TKO and cemented himself as the greatest fighter in MMA history.
