Stephan Patrick Bonnar (born April 4, 1977) is a retired American mixed martial artist who competed as a light heavyweight for the Ultimate Fighting Championship (UFC). Bonnar was the runner up on season 1 of The Ultimate Fighter on Spike TV. Bonnar earned his Taekwondo black belt at the age of 16. He holds notable victories over Brian Ebersole, Terry Martin, James Irvin, Keith Jardine, Mike Nickels, Krzysztof Soszynski, Igor Pokrajac, and Kyle Kingsbury.
Early career 
Bonnar trained in Brazilian Jiu-Jitsu with the legendary Carlson Gracie, under whom he received his purple belt before Carlson's passing. This experience has led to most of his bouts ending by way of submission. Stephan now trains BJJ in Las Vegas under Master Sergio Pehna. However, he also has trained in Muay Thai during several trips to Thailand. Since the beginning of 2010 Stephan has been training Muay Thai in Las Vegas under Master One Kick Nick Blomgren at One Kick's Gym. Stephan is the Ironheart Crown Light Heavyweight champion and Total Fight Challenge Light Heavyweight champion 2002-04.
Mixed martial arts career 
Ultimate Fighting Championship 
Due to his strong performance in the Light Heavyweight finals, where he lost a unanimous decision to Forrest Griffin in a back and forth fight, Bonnar was awarded a six figure UFC contract along with Griffin.
After his loss to Griffin, Bonnar became the staple of the regular UFC Ultimate Fight Night shows at the Hard Rock Hotel and Casino in Las Vegas, defeating such notables as Sam Hoger, James Irvin and Keith Jardine before succumbing to Rashad Evans by way of majority decision. More recently, Bonnar lost a unanimous decision against Forrest Griffin in the long-anticipated rematch at UFC 62. After UFC 62, Bonnar tested positive for the banned substance Boldenone, a type of anabolic steroid. The commission issued a 9-month suspension on Bonnar's fighter's license and fined him $5,000.
Bonnar was forced to withdraw from his fight against Matt Hamill at UFC Fight Night 13 due to a serious knee injury he suffered during training. He returned to action at UFC 94 against Jon Jones, which resulted in a loss via decision. In his next fight at UFC 100 Bonnar lost a unanimous decision to Mark Coleman.
Bonnar mentioned on the MMA Live Post Fight Show for UFC 101 that he was considering a drop down to middleweight after two disappointing losses at light heavyweight. Despite this, Bonnar next faced Krzysztof Soszynski on February 21, 2010 at UFC 110. Soszynski was victorious at 1:04 in the third round, due to TKO (Cut). The fight however, was overshadowed by video replays that showed that the cut was opened up by a clash of heads. Bonnar appealed the decision and it was announced on March 10 that he had lost the appeal and the result would stand as a TKO win for Soszynski.
At UFC 116, Bonnar won the rematch with a second round TKO against Soszynski after catching him with a knee. The win broke Bonnar's three fight losing streak, bringing his UFC record to 6-6. The fight earned Bonnar and Soszynski Fight of the Night honors alongside Yoshihiro Akiyama and Chris Leben's fight.
Bonnar has recently been campaigning for a spot as a coach on The Ultimate Fighter against Forrest Griffin, going as far to state that he would, "Not go for any takedowns, not block any punches, and always move forward."
With the UFC needing to replace the main event at UFC 153, they turned to Bonnar and Anderson Silva to fill the spot left empty by injuries. The two UFC vets squared off in a light heavyweight match October 13, 2012 in Rio de Janeiro, Brazil. Silva won the fight via TKO. Bonnar tested positive for anabolic steroids after the fight (Drostanolone).
Personal life 
Stephan and his longtime girlfriend Andrea Brown were married on October 30, 2009 in Tuscany, Italy. The couple are currently expecting their first child.
Outside of competition, Bonnar has done commentary work for televised MMA programming, notably serving as the WEC's color commentator for most of 2010, calling 5 of their final 7 cards. He has also made appearances as an analyst on the ESPN2 series MMA Live and for UFC broadcasts on the Fox television networks.
