Just yesterday it was revealed that Chael Sonnen had tested positive for banned substances in Nevada. Today, in light of that situation, Sonnen announced his retirement on tonight's edition of UFC Tonight:
“I want to take an opportunity to officially announcement my retirement from competitive mixed martial arts. I had a great time. I want to thank Roy Pittman. I want to thank Dave Sandal. I want to thank my coach Clayton Hires. These guys taught me how fight, they taught me how to persevere and they stood by me through thick and thin.
“I want to thank FOX, I want to thank the leadership of the UFC. I want to thank a man named Bill Brady, who gave me a second wind if you will. He’s a member of the Nevada State Athletic Commission and he believed in me at a time when I really needed somebody too, and I owe the second wind of my career to him. I am proud to call him a friend. I also want to thank the most important opponent I’ve ever had. I couldn’t have got here without this dance partner, and that is of course you, Anderson Silva. Thank you for the opportunity. Thank you for the memories, thank you for the invitation to the barbeque, even though I didn’t take you up on it. “
