According to ESPN.com, Couture has stated that his upcoming fight with former light heavyweight champion Lyoto Machida will be his last.
This is not the first time the former six-time UFC heavyweight and three-time UFC light heavyweight champion has announced his retirement.
His first announcement came after he lost a title fight to UFC legend Chuck Liddell at UFC 57. Couture would later return to defeat then heavyweight champion Tim Sylvia to once again wear UFC gold.
His next announcement came in October of 2007, when Couture was pursuing a possible fight against phenom Fedor Emelianenko and looked to split all ties he had with the Ultimate Fighting Championship.
Although the previous two retirements were short lived, the 47-year-old Couture states that he truly means it this time.
"I believe this is my last fight. I want to stick to my guns, and this is the last one."
He would go on to talk about how with the recent UFC purchase of rival promotion Strikeforce, the UFC may look to use Couture for UFC/Strikeforce "super fights".
However, Couture states that he wants to retire on his own terms.
"I want to go out when I think it's time to go out and not because I lost this fight or lost that fight or because I had an injury that precludes me from training the way I want to train. I want to make the decision on my own."
Couture said that he will still stay active in the mixed martial arts world as both a trainer and personality. He has been seen several times in other UFC fighter's corners, including current lightweight No. 1 contender, Gray Maynard.
"The Natural" has also graced the broadcast table in the past with Joe Rogan and Mike Goldberg, and could serve as a guest analyst for future events.
Couture's final fight will be his 30th professional MMA bout and it will take place in front of 55,000 screaming fans in Toronto's Rogers Centre. Although in Canada, "Captain America" should still receive the praise he deserves as a legend and one of the greats.
