It's hard to believe that it's already been four years since Irish phenom #ConorMcGregor made his first appearance inside the Octagon at UFC on Fuel TV 9.
What's even harder to believe is that, at the time, the mixed martial arts superstar was relegated to a preliminary card bout broadcast live only Facebook (remember those days?). Boy, how things have changed.
While McGregor has seen a meteoric rise with his star power since his debut against Marcus Brimage, he isn't the only fighter who's witnessed his fortune change following that fateful day in Stockholm, Sweden.
Ahead, check out where the winners of UFC on Fuel TV 9 are now.
Out of all the winners from that Fuel TV card, "Notorious" has obviously seen the biggest change with his career, both inside and outside of the Octagon.
In less than four years, McGregor went from being a Facebook prelim fighter to the only person in UFC history to hold belts in two different weight classes at the same time. Now his sights are set on even bigger dreams.
If the Irishman has his way, his next fight will be in a boxing ring against arguably the most skilled pugilist of all time: Floyd Mayweather Jr. Should this match-up actually materialize, you can bet that it won't be streaming for free on social media.
While the UFC on Fuel TV 9 card will forever be remembered for heralding the coming of King Conor, people forget that a different MMA veteran headlined the card.
Since Gegard Mousasi's solid decision win over Ilir Latifi way back in 2013, the former #Strikeforce and DREAM champion has put together a solid run inside the Octagon, going 7-3 with four straight wins in his last four outings. Although he's failed to obtain that coveted title shot, #GegardMousasi has a ton of big victories over the likes of Vitor Belfort, Uriah Hall, and Dan Henderson.
English veteran Ross Pearson hasn't had the best of luck since his 2013 TKO win over Ryan Couture in Stockholm.
Since that victory, Pearson has put together a paltry 4-7 (1) record in the UFC, losing four out of his last five fights. To his credit, the British fighter has faced some stiff competition over the years, taking on the likes of Gray Maynard, Diego Sanchez, Melvin Guillard, Will Brooks, and Jorge Masvidal.
However, should he fail to beat Dan Hooker at #UFCNewZealand later this year, it's hard to envision a future for Pearson with the UFC.
Heavyweight powerhouse Matt Mitrione has seen his stock rise, fall, and rise again since his 19-second KO of Phil De Fries at UFC on Fuel TV 9.
The former NFL player went 3-3 following the 2013 victory, with solid finishes over Gabriel Gonzaga, Derrick Lewis, and Shawn Jordan. However, Mitrione decided to abscond to #BellatorMMA following his gruesome TKO loss to Travis Browne in Boston last year.
Since moving to Bellator, though, Mitrione has gone a perfect 2-0 and is now set to face MMA's greatest heavyweight, Fedor Emelianenko, on the promotion's upcoming PPV event in New York City. Hopefully this fight actually happens this time.
Fan favorite Brad Pickett has had a lot of great moments as a fighter, however, is Fight of the Night winning performance over Mike Easton at UFC on Fuel TV 9 was unfortunately the beginning of the end for "One Punch."
The English fighter had an extremely rough run in the UFC following his win in Stockholm, going just 2-7 until his retirement earlier this year. Pickett decided to call it quits following his head kick TKO loss to Marlon Vera at #UFCLondon.
While it was a tough way to end such an amazing career, fans will always remember Pickett's power and grit.
The MMA world hasn't seen much of Tom Lawlor since his submission win over Michael Kuiper in 2013, as he's only fought twice following the victory.
Injuries kept the always entertaining Lawlor on the sidelines for close to two years, but he came back with a vengeance in 2015, knocking out Gian Villante just 27 seconds into the second frame. Lawlor followed up the win with a tough fight against Corey Anderson at UFC 196, which ended up as a decision loss on his record.
Unfortunately, a recent failed drug test means fans won't get to see Lawlor in the Octagon for the foreseeable future.
Former TUF winner Diego Brandao looked like a contender to watch following his 2013 submission win over Pablo Garza. While he followed up the victory with a decision win over Daniel Pineda, Brandao had a rough patch in his final string of bouts for the UFC.
Brandao was finished in back-to-back fights when he took on McGregor and Dustin Poirier after his victory against Pineda. Although he put together consecutive first finishes in 2015, Troubles outside of the Octagon led Brandao to eventually lose his UFC roster spot following a triangle choke loss to Brian Ortega at UFC 195 last year.
Brandao's post UFC career is off to a solid start, though, as he helicopter armbarred his way to victory against Murad Machaev in Russia earlier this year.
Akira Corassani lived out his dream at UFC on Fuel TV 9 by beating Robbie Peralta in his home country of Sweden. However, Corassani's UFC career didn't last long following the big win.
Corassani was 1-3 in his last four fights for the promotion, and lost via KO in back-to-back fights against Sam Sicilia and Max Holloway. After his loss to Sicilia, which also took place in Sweden, Corassani decided to call it quits and announced his retirement on Facebook the following day.
Reza Madadi impressed fans with his submission win over Michael Johnson in 2013. But following the victory, the Iraniah-Swedish had to get his life together before returning to the UFC, as he was convicted on burglary charges.
Madadi can back to the promotion in 2015, though, to face Norman Parke in Dublin. Although Madadi ended up on the wrong end of a decision, he bounced back from the loss by TKOing Yan Cabral in 2016.
The MMA veteran most recently fought against Joe Duffy at UFC Fight Night London, but once again came up short on the score cards.
Sweden's Tor Troeng felt pretty good after his win over Adam Cella at home in 2013. However, the good vibes didn't last long.
The TUF alum would go on to lose his next three fights, including a Fight of the Night performance against Rafael Natal. "The Hammer" officially retired following his 2014 loss to Krzysztof Jotko.
Russian fighter Adlan Amagov hasn't been all that active since his win over Chris Spang in 2013. Although Amagov followed up the victory with a KO over TJ Waldburger at UFC 166, "The Wolf" effectively retired from competition after the win.
Amagov did return to the cage in 2016, though, as he faced Dirlei Broenstrup in Russia. Amagov went on to win the bout via first round submission.
Papy Abedi is another fighter who hasn't had the best of luck since UFC on Fuel TV 9.
Following his split decision win over Besam Yousef in 2013, Abedi went on to lose in brutal fashion to Dylan Andrews later that year. The KO defeated ended up being Abedi's last fight in the UFC.
Following his split with the promotion, Abedi has been plagued with injuries and has only fought twice. His most recent bout was a rematch with Andrews, who would again knock out Abedi during their middleweight title fight at Superior Challenge 15.
Ryan LaFlare didn't become a superstar after UFC on Fuel TV 9, but he has put together an impressive record for the promotion.
After his win over Ben Alloway, LaFlare has amassed five victories inside the Octagon, with his sole loss in that time span coming at the hands of Demian Maia. LaFlare most recently defeated Roan Carneiro via unanimous decision at UFC 208.
