Which MMA Fighter Will Test Positive For Steroids Next?

The Seven Nastiest Illegal Knockouts of All Time

(Perfectly legal, mind you.)

Ah, the good old days — when men were men, women were women, and ballsacks could be repeatedly pummeled inside the Octagon without Big John McCarthy doing a damn thing about it. Above, of course, is the fateful UFC 4 fight between Keith “By Any Means Necessary” Hackney, and Joe Son (who later appeared as Random Task in the first Austin Powers movie). By the late ’90s, rule changes had made mixed martial arts look somewhat civilized, and dozens of attacks/holds/gouges were deemed verboten. But regrettably, accidents still happen. And now, our favorite “accidents” ever…

7. Anderson Silva upkicks Yushin Okami

Before The Spider was the deadliest dude in the UFC, he was just a guy trying to get Yushin Okami the fuck off of him at Rumble on the Rock 8. His knockout kick was a crowd pleaser, but unfortunately he was DQ’d on a technicality — Okami’s knees were down.

6. Andrei Arlovski rabbit-punches Marcio Cruz
After back-to-back losses at the hands of Tim Sylvia, Arlovski was dying for a win, and he wasn’t above fighting dirty to get it. When the opportunity presented itself at UFC 66, the Pitbull started whaling on the back of Marcio Cruz’s head. Herb Dean gave him a warning. Arlovski kept doing it. Herb Dean warned him again. Arlovski kept doing it. Herb Dean stopped the fight and gave Andrei the win. Love that Herb Dean.


5. Roger Huerta knees John Halverson in the head
A 19-second knockout win is pretty damn impressive — even if it is total horseshit. But hey, we can look the other way for a poster boy.

4. Wes Sims stomps Frank Mir

Sims momentarily thought he was in a PRIDE ring during UFC 43 and stomped Mir out for a DQ loss. Mir would have his revenge in a rematch seven months later, knocking Sims out fair and square.

3. Quinton Jackson headbutts Ricardo Arona

To the announcers and audience at PRIDE Critical Countdown 2004, it was Rampage’s dramatic power-bomb slam that put Arona’s lights out. Arona, however, claimed it was the illegal headbutt directly after that caused the K.O. We’ll call this one unintentional, but the cuts on Jackson’s face at the 2:33 mark of the video do kinda look like they were made by teeth…

2. Mike Kyle soccer-kicks Brian Olsen

What the hell got into this guy? Mike Kyle let the warrior spirit overtake him at WEC 20, as he ignored the rules outlawing soccer-kicks and punching unconscious opponents after the fight has been stopped. Absolutely brutal. Whatever ‘roids he was on, I want a month’s supply.

1. Gilbert Yvel knocks out referee

Notoriously dirty fighter Gilbert Yvel has bitten Karimula Barkalaev and eye-gouged Don Frye, but nothing compared to his November 2004 match with Atte Backman, in which he actually punched out a referee who got in his face one too many times, then kicked him while he was down. Apparently, it’s always illegal to strike a ref (even if his knees are off the ground) and Yvel picked up his third loss by DQ. Kudos, Gilbert — you’re a credit to the sport.

Did we forget any good ones? Let us know in the comments section.

oooooooooow guy,that was too harsh video to kich the bloody ass lower ...

I haven’t checked every one of these but did anybody mention Heath’s pre-match KO when his opponent tried to experience mindgames by kissing him?

Texas Crazy-horse’s are very concerned about not turning up homosexual as Heath may be heard shouting after he clocked him. Lol.

Keith Hackney didn't hit the nuts HALF as much as Royce Gracie did. Not as hard either, as Joe Son (founder of JoeSonDo lol) was later charged & convicted of rape! Royce also pulled hair...

Both Riggs knees are clearly of fthe mat when sanchez his him.
durrrrrr- March 26, 2009 at 5:40 pm
FYI Arlovski wasn't punching to the back of the head. Most of those punches hit the guy around or just behind the ear. Not the back of his head ( 1 inch wide area from the crown of you head to the base of your neck ). GREAT job reffing Dean, 90% of MMA fans don't even know what the real definition of back of the head is.

For the Riggs - Sanchez fight, Riggs had both knees off of the ground so it was legal. Just watched it last night.

Regarding Huerta,

They replayed it and you could see it did NOT hit the head. This is not fans simply defending a fighter, the different angle clearly showed it land on the shoulder.
Pestos- February 10, 2009 at 5:08 am
So he had a mouthguard on his bottom row of teeth too? Watch the fight a couple of times and you clearly see the headbutt caused the cut, teeth or not, but who knows if Arona was out before.

Another weird knockout was Tito vs Evan Tanner "slam" knockout, which was DEFINATLY a headbutt causing the knockout.

And what about Matt Hughs vs Carlos Newton? Hilarious to watch though, looks like they give a win to whoever wakes up first!

i'm no fan of huerta but that knee was legal for sure. no doubt. and yes a list of WORST REF"D FIGHTS is in order and herb dean better get top honors. i would also like a FUNNIEST MMA QUOTES list, you know while we're making requests here...

You haters can go to hell.

This site has interesting articles and vids and always makes me laugh. I could give a damn if they were wrong about some of those clips being illegal.

Enough about that. I wanted to comment on the rabbit punch rule. I feel that if a fighter gets themselves into a position where the back of their neck is exposed and they are turtled up like often happens after a failed single leg takedown their opponent should be able to make a striking motion to the back of the neck to prove he could stike it if he wanted to.

At that point the ref should stand the fight back up and penalize the turtled fighter 1 point.

I know some of you will think that sounds gay but imagine if the rear naked choke were considered dangerous and someone could just leave his neck wide open while trying to escape from back control and the opponent who worked for that superior position couldn't do anything to capitalize on it.

these grapplers who are constantly trying for takedowns and getting stuffed should have to pay for their failures that leave them vulnerable to a potentially career ending strike with penalties and eventual disqualifications just like stikers who make mistakes in grappling have to pay with being submitted.

WTF, you bitchy whiny pusses, most of those were just tough shit. STFU

MMA should not be called a Martial Art. Since when did any real martial art ban kicking someone in the head or punching someone in the groin. This shit is a fucking sport parading as a martial art.

This sucks, half the videos don't work.

Seven nasty knockouts? Try three half-ass ones and a shitty flash video. The number one video doesn't even work. Give me a break cagepotato.

I don't care what any of you say about Herb Dean. I saw him naked once, and he is hung like a bull moose! When I saw his mammoth man meat, I decided that Herb was the greatest referee in the world.
tommy- May 4, 2008 at 9:07 am
In the AA vs Cruz fight ...Herb tells them both to stand up but Cruz doesn't want to stand up ,so for some reason Herb lets them stay in position(since Cruz asks so nicely) ,then when herb says go Andre immediately hits Cruz with a legal blow. and then finishes him of with blows to the head but NOT to the back of the head...Herb is saying watch the back of the head and Andre complies. I like Cruz to but he lost this one fair and square.

beep did Herb get to Mike Kyle so quickly? He's never saved anybody so quick in his career!
