The UFC's popular series The Ultimate Fighter is currently in the middle of Season 18. The franchise has cultivated several title contenders as well as some of the most popular fighters that the sport has ever known.
Bleacher Report continues our retrospective on the reality series this week by taking a look back at the stars of Season 4: the controversial "comeback" season.
Season 4 centered on the idea that everybody deserves a second chance. Two fighters would earn a title shot. Several fighters would earn a return bout on the show's finale. Some would be unable to capitalize on their opportunity and fade away into the abyss.
Here is a look at the cast of The Ultimate Fighter 4: The Comeback.
Rich Clementi fought nine times in the UFC after living in the TUF house. With a 5-4 record during that stretch, "No Love" was able to secure notable wins over Anthony "Rumble" Johnson, Melvin Guillard and Sam Stout.
The New Jersey fighter was released from his Zuffa contract after consecutive losses to Gray Maynard and Gleison Tibau. Since that time, Clementi has competed 21 times in various promotions around the world, putting up a 12-9 record.
Clementi most recently competed against Ricardo Tirloni on September 27 as part of the Bellator Season 9 lightweight tournament. No Love lost a one-sided unanimous decision.
Mikey Burnett controversially lost a fight against Pat Miletich in 1998 that was to determine the inaugural UFC welterweight champion. Were it not for the poor decision from those judges, the pioneer would have a much different life today.
During a training session on the show, Burnett suffered a career-ending spinal injury. This went undiagnosed until after his tournament fight with Din Thomas, which he lost via triangle choke.
Burnett has not fought professionally since 1999, where he won a decision at UFC 18.
Jeremy Jackson may best be remembered as the guy who got removed from the TUF 4 tournament after leaving the confines of the mansion without permission. However, his MMA legacy will be based around his 2002 knockout victory over Nick Diaz.
Jackson surprisingly got a bid on the show's finale, where he lost to Pete Spratt and was not invited back.
In 2008, Jackson was arrested and charged with multiple counts of aggravated rape. After pleading guilty to the charges, he was sentenced to 25 years to life in prison, effectively ending his MMA career.
Pete Spratt peaked when he chopped down Robbie Lawler with leg kicks in 2003. However, the UFC didn't seem willing to accept that when booking "The Secret Weapon" as a cast member of TUF 4.
After being eliminated by Matt Serra, Spratt replaced Jeremy Jackson in the opening round, where he was delivered a second tournament loss, this time at the hands of Din Thomas.
Spratt defeated Jackson at the show's finale, but that was where his success stopped. Never one to build much momentum, Spratt was submitted by Marcus Davis and Tamdan McCrory before his release.
Since being dropped from Zuffa, Spratt has competed 20 times in various organizations. His 10-10 record during this stretch is highlighted by a wins over Luigi Fioravanti and TJ Waldburger. At no point since the show has Spratt won more than two consecutive fights.
After being knocked out by Tim Means on September 13, Spratt announced his retirement from the sport. However, he later announced that he isn't retired and plans to appeal the loss.
Within the MMA community, few fighters have been shamed the same way as Travis Lutter. After using his jiu-jitsu prowess to dominate the middleweight field, "The Serial Killer" earned a crack at the UFC middleweight championship.
Despite being granted a golden opportunity by walking through a field of non-contenders, Lutter showed a complete lack of appreciation and professionalism by coming in overweight. The bout was changed to a non-title affair, and Lutter was submitted in the second round.
After being finished in followup fight against Rich Franklin, Lutter was released from the UFC. Eighteen months later, he defeated Jason MacDonald on a regional show, which remains his only victory since the tournament final.
Lutter has not competed since a miserable showing against Rafael Natal in 2010. In that fight, the would-be title contender was both gassed and knocked out in the first round.

Charles McCarthy didn't accomplish much during his MMA career. His 10-5 record is full of victories over tomato cans, and he was only brought onto the show due to the vicious nature of his 2005 loss against David Loiseau.
He didn't accomplish much afterward, either. However, for every problem he faced inside the cage, "Chainsaw" had a success outside.
McCarthy got out of the cage for the last time after being teed off on in Michael Bisping's middleweight debut. Not only did he open a school where he trains fighters, but he is a partner at Alchemist Management.
Gideon Ray might still have nightmares about his time in the Ultimate Fighter house. It was there that the poor man was held down by Edwin Dewees while the bleach-blonde youngster bleed like a stuck pig into his face and mouth.
Ray was eliminated in the first round of the tournament and was submitted by Charles McCarthy at the show's finale. That was the last time UFC fans saw the now 40-year-old.
Ray competed on a regional card in December, where he lost to UFC washout Shamar Bailey. That brings his post-UFC record to an appalling 4-10.
After being eliminated in the first round of the TUF 4 middleweight tournament, few could have predicted that Jorge Rivera would fight 10 more times inside the Octagon.
Not only did Rivera have a memorable (and hilarious) feud with Michael Bisping, but "El Conquistador" scored vicious knockout wins over Kendall Grove and Nate Quarry.
On the cusp of his 40th birthday, Rivera finished opponent Eric Schafer and announced his retirement from mixed martial arts. You can follow him on Twitter, but he mostly shares religious passages and movie quotes.
Pete "Drago" Sell was a semifinalist of the middleweight tournament on The Ultimate Fighter, but his most memorable career moment came during the show's finale.
After an epic war against housemate Scott Smith, Sell appeared to finish his opponent with a nasty body shot. As he charged forward to finish, Smith landed a brilliant shot that put Drago to sleep. The fight is considered to be one of the most exciting in history.
Sell went 0-3 after the show and was released from his contract. However, booked as an assistant coach for Matt Serra on Season 6 of TUF, Sell was given another chance inside the Octagon, where he went 1-1 before being fired once again.
At the age of 31, it is unlikely that he has hung up his gloves, but Sell has not competed since February 2012.
Tournament finalist Chris Lytle lost a split decision to Matt Serra, and it cost him his chance at winning gold inside the Octagon. However, that didn't stop him from becoming one of the most popular and exciting fighters that the sport has ever known.
"Lights Out" looked to make a run at the UFC welterweight championship in 2010 after recording impressive wins over Matt Serra, Matt Brown and Brian Foster. However, those hopes were dashed when Lytle was upset by late replacement Brian Ebersole at UFC 127.
In his final fight, Lytle won a headlining bout against Dan Hardy in a thrilling affair that saw the submission specialist secure a guillotine with only 44 seconds left in the bout.
Lytle's legacy will ultimately lie in his caution-to-the-wind style that won him a whopping six Fight of the Night awards. Winning another four Fight Night bonuses in other categories, the firefighter held the record for most bonus awards at the time of his retirement.
Scott Smith has had an interesting run since his time on The Ultimate Fighter. The heavy-handed striker was a notable middleweight in second-tier organizations.
"Hands of Steel" twice competed for the EliteXC championship against Robbie Lawler and handed Cung Le his first professional defeat by way of knockout back in 2009.
The victory over Le was the last major win that Smith obtained. Since that time, the 34-year-old dropped four consecutive losses under the Strikeforce banner before being released from his Zuffa contract.
Smith competed in August, winning a fight on the regional circuit against Mark Matthews. It was his first victory in nearly four years.
One of the few fighters from TUF 4 to still remain in the UFC, Patrick Cote is the only non-winner of the show to earn a championship opportunity inside the Octagon.
Cote's crack at the UFC middleweight championship came on the heels of a five-fight win streak. He became the first man to make it into the third round against Anderson Silva.
The Canadian was released from his contract in 2010 but returned after winning four bouts on the regional circuit. "The Predator" is 2-1 during his current Octagon stint and has moved to the welterweight division.
Representing his home country, Cote will coach an international version of TUF opposite Australia's Kyle Noke. The season will debut in early 2014.
Most MMA fans who remember Edwin Dewees think of the baby-faced fighter as the bleach-blonde TUF house guest who bled all over a helpless Gideon Ray.
At the relatively young age of 28, Dewees became one of the youngest fighters to compete in 50 professional fights in early 2011.
The last major event in which Dewees competed saw him knocked out by Antonio "Lil Nog" Nogueira at Affliction: Banned.
Since being eliminated from the tournament, "Bam Bam" has compiled a 3-7 record.
Always known for a certain amount of flair and panache, Shonie Carter is arguably the flashiest fighter to ever step into the Ultimate Fighter house.
Carter is one of few cast members who did not participate at the TUF 4 Finale. However, he was invited back to compete at UFC Fight Night 7, where he lost a unanimous decision to Marcus Davis. It was his final fight with the organization.
Now retired, Carter competed 24 more times before hanging up his gloves. "Mr. International" lost 10 of his final 12 fights.
Once considered to be a top-ranked lightweight, Din Thomas holds career wins over UFC champions Jens Pulver and Matt Serra. He was eliminated from the TUF 4 tournament by Chris Lytle in the semifinal round.
Winning post-show bouts against Clay Guida and Jeremy Stephens, Thomas looked to again be a major player in the lightweight division back in 2007. Unfortunately, consecutive losses to Kenny Florian and Josh Neer saw "Dinyero" surprisingly released from the organization.
Thomas dropped to featherweight after leaving the UFC, where he won his first four fights. The last of those came against touted prospect Cody Bollinger, but was changed to a no-contest.
Thomas made headlines in 2010 when a scheduled bout against boxing champion Ricardo Mayorga was cancelled at the last minute thanks to Don King.
Most recently, Thomas dropped a decision to Georgi Karakhanian back in April.
After defeating Chris Lytle in the tournament final, Matt Serra went on to shock the world at UFC 69 when he knocked out Georges St-Pierre. To this day, the victory is considered to be the biggest upset in MMA history.
Becoming the first TUF contestant to return as a coach, Serra was scheduled to defend his belt against rival Matt Hughes. However, a herniated disc in his back forced "The Terra" out of the contest and led to an interim title bout between Hughes and GSP.
GSP dominated Serra in the rematch, and the New Yorker lost a razor-thin decision to Hughes when their grudge match finally went down.
In his final two fights before retirement, Serra knocked out Frank Trigg and came up short in a thrilling rematch against Chris Lytle at UFC 119.
Serra has spent time as an interviewer working for the UFC during its Fight Camp Insider series.
These days, Serra continues to coach alongside Ray Longo. Their students are doing quite well for themselves inside the Octagon. You might be familiar with them: UFC middleweight champion Chris Weidman, ranked middleweight Costa Philippou and lightweight prospect Al Iaquinta.
