About Sean Sherk

Born 1973. Sean Sherk is an American mixed martial arts fighter.

Sean Keith Sherk (born August 5, 1973) is an American retired mixed martial artist and former UFC Lightweight Champion. Sherk competed in the Ultimate Fighting Championship and was one of the first combatants to have been a championship competitor in multiple weight divisions (having also competed for the UFC Welterweight Championship). He was the second UFC Lightweight Champion in the organization's history after Jens Pulver vacated his title five years earlier. Sherk also spent time competing in the Japan-based organizations, PRIDE Fighting Championships and Pancrase; going undefeated in both promotions. He holds one of the longest undefeated streaks in mixed martial arts history, with only four career losses, all to fellow-UFC Champions. Sherk announced his official retirement from mixed martial arts competition in September 2013 having last fought three years prior.

Recognized for his role in the resurgence of the UFC Lightweight division, Sherk became the first UFC Lightweight Champion since the division was re-introduced by the UFC in 2006. He successfully defended the UFC Lightweight Championship against Hermes Franca at UFC 73, after winning the title in a Fight of the Night award winning performance against Kenny Florian at UFC 64. Sherk is noted to have taken part in some of the most important fights in the UFC's lightweight division, where he is considered to be one of the greatest lightweight competitors of his era.

Martial arts background Sherk was born on August 5, 1973, in St. Francis, Minnesota. Sherk began Wrestling and Weightlifting at age seven. After finding Greg Nelson's Minnesota Martial Arts Academy in 1994, Sherk began to practice Judo, Boxing, Shootfighting, and Muay Thai.

Mixed martial arts career Sherk began his mixed martial arts career in 1999, where he went on an eight-fight win streak before signing with the Ultimate Fighting Championship (UFC) in 2001.

Pride (2004) Following his loss to Hughes, Sherk fought three more times in 2003, winning all three bouts. but was given another fight in the UFC at UFC 59, Sherk demonstrated that he was able to stand and strike with the more documented striker in Nick Diaz as well as mixing his combination very well with his takedowns, he defeated Nick Diaz via unanimous decision. During the post-fight interview, Sherk stated his intention to drop down in weight to the lightweight division. With this win, Sherk became the first UFC Lightweight Champion since Jens Pulver vacated the title in 2002.

Steroid accusations

In July 2007, Sherk successfully defended his title against Hermes França at UFC 73. After the fight, the California State Athletic Commission (CSAC) announced that Sherk had tested positive for Nandrolone, a banned steroid, in a urine test the day prior to the fight. After testing positive for 12 ng/ml of Nandrolone, Sherk was fined $2,500 and suspended from competing in California for one year. Sherk's suspension was reduced to six months after appealing his allegations on December 4, 2007, making him eligible to fight in early January 2008. Sherk argued that errors were made in lab testing procedures. He asserted that the lab had failed to properly test the vials used in earlier, positive tests for any remaining steroid content, which may have resulted in his sample becoming contaminated. Quest Diagnostics and the CSAC denied any errors were made. At UFC 80, B.J. Penn defeated Joe Stevenson to win the vacant title. After the fight, UFC president Dana White announced that Penn's first title defense would be against Sherk, who was reinstated by UFC in April 2008, and has tested clean ever since. Sherk and Penn fought at UFC 84 on May 24, 2008. Sherk lost by TKO in the third round after failing to answer the fourth round bell.

After UFC 84

Sherk fought Tyson Griffin at UFC 90: Silva vs Cote, in a fight with title contention implications. In a three-round war, Sherk won by unanimous decision, earning him a $65,000 Fight of the Night award. In the first round Sherk was putting the pressure on Griffin from the very beginning scoring take-downs and taking Griffins back. Throughout the second and third rounds Sherk took Griffin down once more and the rest remained an exciting striking battle between the two. Sherk demonstrated very crisp and technical striking that night.

Sherk next fought Frankie Edgar at UFC 98 losing via unanimous decision. Sherk again found himself in trouble with an athletic commission post fight, after he ran from the arena while still in his fight shorts and no shirt before supplying a post fight urinalysis. He was contacted by commission officer Keith Kizer and told to return to the arena immediately or face his license being revoked. Sherk returned within the hour and provided a urinalysis and tested clean, but was still suspended 45 days for the actions.
