No person is invincible, no matter how great they are.
All the greats in MMA have lost, including Royce Gracie, Matt Hughes, Anderson Silva and Georges St.Pierre to name just a few.
MMA fans around the world thought Fedor Emelianenko would never lose again. The only loss for Emelianenko at that time was in his fourth fight, when he lost to Tsuyoshi Kohsaka at Rings: King of Kings 2000 Block B, when the fight was stopped 17 seconds into the fight due to a cut to Emelianenko's head.
Footage showed that the cut was caused by a punch where Kohsaka's elbow struck Emelianenko's head. Elbow strikes were illegal under RINGS rules unless the striker was wearing elbow pads, which Kohsaka was not.
A lot of people really don't consider that a loss for Emelianenko, regardless of the official record.
Fedor had been the Pride Heavyweight Champion and the 2004 Pride Heavyweight Grand Prix Champion before Pride folded.
After Pride folded, Fedor went on to fight under the Bodog and Affliction banner before signing with Strikeforce in 2009. After defeating Brett Rogers in November of '09, Fedor was scheduled to fight Fabricio Werdum on June 26, 2010.
Werdum, who had also fought in Pride from 2004-2006 with a record of 5-2, headed into the UFC in 2007. There, he lost a unanimous decision fight against former heavyweight champion Andrei Arlovski at UFC 70.
Werdum complied a robust 2-2 record in the UFC and was released after his knockout loss to now heavyweight champion Junior Dos Santos at UFC 90 in October of 2008.
Going into this fight, no one really thought Werdum had a chance. Fedor was on a 28-fight winning streak. People were targeting a fight between Emelianenko and then Strikeforce heavyweight champion Alistair Overeem.
To start the fight, Fedor knocked Werdum down with a combination of hard punches. But then he made a huge blunder, going to the ground with Werdum, who was regarded as the best in the MMA at Brazilian jiu jitsu.
Werdum put Fedor in a triangle armbar and Fedor tapped out 69 seconds into the fight.
It was considered one of the biggest upsets in MMA history.
Emelianenko lost two more fights in a row before getting released by Strikeforce last year. Fedor went on to win three more fights for M-1 Global and Dream before retiring after his win over Pedro Rizzo in June.
Werdum used the win to springboard into the elite in the heavyweight division and will be coaching TUF Brazil starting in early 2013.
