Bonnar (15-8) will always be remembered for his classic fight at The Ultimate Fighter 1 Finale against Forrest Griffin in 2005. This fight is the bout that changed the sport and was the catalyst for the rise of mixed martial arts.
He would never make his way to a title shot in the UFC, but fought some of the best fighters in the world including Silva, Jones and Rashad Evans. Prior to his fight with Silva, he had been on a three fight winning streak with wins over Krzysztof Soszynski, Igor Pokrajac and Kyle Kingsbury.
If this is the end of the career of Bonnar, he will likely be one of the next inductees into the UFC Hall of Fame.
