Stephan Bonnar Officially Retires From MMA

After spending nearly twelve years as a competitive mixed martial artist, light heavyweight Stephan Bonnar (15-8) has called it quits. 

While Bonnar has yet to publicly announce the news, UFC President Dana White revealed on Tuesday evening during a Metro PCS chat that the 36-year-old is done.

"Yes, Bonnar will be retiring now," White responded when asked by a fan about Bonnar's future.

The news comes just two weeks after a first round technical knockout loss to pound-for-pound king Anderson Silva in the UFC 153 headliner. Bonnar, who had previously expressed interest in hanging up his gloves, took the Silva fight on short notice after the event's original headliner was scrapped due to featherweight champ Jose Aldo suffering an injury. 

The defeat snapped a three-fight win streak, which included victories over Krzysztof Soszynski, Igor Pokrajac and Kyle Kingsbury. 

With a UFC record of 8-7, all but one of his career defeats came at the hands of current or former champions: Lyoto Machida, Forrest Griffin, Rashad Evans, Jon Jones, Mark Coleman and Anderson Silva.

Bonnar's famous three-round brawl with Griffin at The Ultimate Fighter Finale in 2005 is often credited with helping save the Ultimate Fighting Championship from a possible demise, and is widely considered amongst the greatest fights in MMA history.
