The world of mixed martial arts is filled with a lot of talented and dedicated men and women who have dedicated their lives to their craft. However, for every hard-working and talented fighter, there is at least one bum. And by some miracle of fate or dumb luck or angelic revelation, some of those terrible fighters made their way to the biggest company of all.The UFC is the place to see the best fighters on the planet face off against one another, but that is not always the case. Recently, the UFC has become over-saturated with fighters as the company tries to meet viewer demand. The Ultimate Fighter has brought along fighters much faster than they likely should have which has caused a bumper crop of poor fighters. And we can add to that the early days of the company, which basically pitted a lot of bone-headed street fighters against one another in some machismo filled contest.We all know the best fighters in history; the Randy Couture’s and Royce Gracie’s, but what about the worst. The fighters that are not much more than a stain on the underpants of the world of MMA. We have opened the annals of the UFC history books to check out the worst fighters to ever enter the octagon.We looked at the fighters with the least experience in MMA, the fighters who were thoroughly beaten down within the octagon and those fighters who had practically no legitimate martial arts experience. And without further ado, here are the 15 worst fighters in the history of the UFC.

10 Moti Horenstein (UFC Record: 0-2)

Horenstein was always an amazing striker. ‘The Hammer’ was a former Israeli commando and master of Krav Maga, a unique style developed to focus on real world scenarios. However, Horenstein was useless if he ever went to the mat.

The worst possible outcome came when Hohenstein drew Mark Coleman, a division one national wrestling champion, at UFC 10. Things went from bad to worse when he fought Mark Kerr, another national champion wrestler, at UFC 14.

Combined, ‘The Hammer’s” entire UFC career lasted less than five minutes.

9 Rolles Gracie Jr. (0-1)

The Gracie family is meant to be MMA royalty, but Rolles Gracie Jr. was merely a court jester.

Rolles was rushed into the UFC after only three professional fights, no doubt due to his name. After his original opponent, Mostapha al-Turk, had to withdraw from the fight due to visa issues, the UFC placed slugger Joey Beltran against Gracie.

Rolles was not prepared for a fight no matter who the opponent after he gassed very early on and ended up being forced to turtle and getting pounded until Herb Dean stopped the fight.

8 Seth Petruzelli (0-4)

How this guy kept getting work in the UFC I will never know. Petruzelli’s biggest claim to fame is beating Kimbo Slice, so you know his career was simply not that good.

Petruzelli got knocked out of TUF and then lost his first two fights in the UFC. After taking some time away from the UFC and gaining some momentum to match his over-the-top personality, Petruzelli promptly got his ass kicked twice in a row.

Petruzelli has managed to lose his final two fights, both in 2013 with Bellator, in a combined four minutes and 26 seconds.

7 Gilbert Yvel (0-3)

By the time Yvel actually made his UFC debut in 2010, he had been in the fight game for over 13 years. And despite proving to be a respectable fighter, there was little doubt that Yvel was an over-the-hill fighter that was getting fed to young guns.

Yvel met a young, un-and-comer by the name of Junior dos Santos in his first career UFC fight which saw the Dutchman get TKOed in the first round.

One of his three losses in the UFC did manage to go the distance, but the other two saw the aging Yvel never make it past the two minute and 10 second mark.

6 James Toney (0-1)

We're absolutely not saying that James Toney was a bad boxer, as the guy did ended his career with a 76-10-3 record, but he was never meant to see the inside of the octagon.

Toney was signed and thrown into a fight with Randy Couture (yes, THAT Randy Couture). To the shock of absolutely nobody, Couture took Toney down within seconds and proceeded to beat the hell out of the boxing champion.

‘Lights Out’ was so ill prepared to enter the octagon that he did not seem to even know how to tap out properly when Couture ended the fight with a choke.

5 Kimbo Slice (1-1)

There was a time when Kimbo Slice was one of the most popular names in fighting. Back in the early 2000s, when people really started getting into YouTube, fighting fans loved watching Kimbo Slice annihilate people in unsanctioned street fights. It wasn't technical, it wasn't pretty, but it was a ton of fun to watch.

Then, Kimbo tried to get serious about fighting. He fought in EliteXC, going 3-1, before getting a shot in the UFC on The Ultimate Fighter, where he lost in the opening round to Roy Nelson. Not a great start.

He'd win at the Finale by decision against Houston Alexander (a terrible fight), but get crushed in his next fight against Matt Mitrione, who was fighting in his second professional MMA fight and who was also a contest of The Ultimate Fighter with Kimbo. Kimbo looked out matched and was subsequently released by the UFC. All that hype led to pretty much nothing, earning a spot for Slice on this list.

4 Tiki Ghosn (0-4)

I have absolutely no sweet clue how Ghosn kept getting calls from the UFC. Ghosn managed to lose four consecutive fights, all by stoppage, in his UFC career.

Ghosn, who appeared on two seasons of the Ultimate Fighter as an assistant coach, lost his first two fights by submission. After promptly getting canned, he came back to get knocked out by Robbie Lawler, left again and got chocked out by Chris Lyle upon his final return.

All things said, Ghosn averaged less than six minutes per fight across four years in the UFC.

3 Gabe Ruediger (0-3)

A lot of stupid stuff has happened in TUF to make a man embarrassed, but none more so than Ruediger. This guy was in the fighters house eating ice cream cake before weigh-ins, then cried the entire time as he tried to cut weight in the sauna. Ruediger was then promptly kicked off the show, so you would logically be surprised when he made his debut in the UFC four years later.

‘Godzilla’ was brought in as an injury replacement getting thoroughly beat down by Melvin Guillard. Ruediger came back again, four years later, to lose two consecutive fights by stoppage.

2 John Alessio (0-5)

There has been no other fighter in UFC history to go 0-5. Alessio was trained in Brazilian Jiu-Jitsu and kickboxing, while being an ‘okay at-best’ type fighter in other promotions, but was completely outclassed in the UFC.

Alessio’s first UFC fight happened in June 2000, when he faced Pat Miletich for the Welterweight title. Then Alessio’s 12-year long journey in the UFC was underway.

The Canadian lost two more fights in 2006, then back-to-back matches in 2012.

Despite the high-profile losses, Alessio is still fighting but has gone just 1-3 with two no contests in his past six fights.

1 Emmanuel Yarborough (0-1)

If somehow you would not have guessed this on your own, here goes: sumo wrestling does not translate well to the UFC. Yarborough was a renowned sumo wrestler and a mediocre division two offensive lineman, but somehow was convinced his talent for pushing bug guys around for short bursts of time would give him success in MMA.

Even though Yarborough weighed in the 600 lbs range, Keith Hackney, a fighter who was roughly 400 lbs less and was competing in mixed martial arts for the first time, put him down within two minutes.
