UFC president Dana White has revealed that Georges St. Pierre (GSP), one of the most decorated UFC fighters of all time, will not be making his return to the Octagon, as he is done with fighting.

The former UFC welterweight champion, who turns 35 in May next year, has been out of action from the cage for around two years and hasn't fought since UFC 167 on 16, November, 2013, at the MGM Grand Garden Arena in Las Vegas.

GSP defeated Johny Hendricks via a controversial split-decision in the main event of the fight card, and just a month later, on 13, December, 2013, the Canadian kyokushin karateka surrendered his title, and announced his indefinite break from mixed martial arts (MMA) owing to personal and professional reasons.

He also left the door for a possible return in the future.

However, following close to two years, White confirmed that GSP, who remained the No 1 ranked welterweight UFC fighter in the world for several years, could have fought his last in the octagon. 

"I don't think so, buddy. I'm sorry," White answered when asked about St-Pierre at a Q&A session in Australia. "GSP's rich, he's hanging out, he's living the good life."

"In this sport, you have to be hungry, you have to jump out of bed every day and want it, you got to want to win. You've got to want to be a world champion. He's had it. He's accomplished all that stuff," White said.

"He's made a lot of money, he's accomplished a lot of things, and I don't see him ever coming back, no."

St-Pierre announced in March last year that he had torn his ACL (anterior cruciate ligament) while training, but following surgery, he was medically cleared to resume training in October last year.

GSP also played as the coach for Rory MacDonald ahead of his welterweight bout against Robbie Lawler at UFC 189 in July this year.

Georges St. Pierre has remained the UFC welterweight champion of the world, on two occasions, and was also the interim UFC welterweight champion in 2007. He defeated Matt Serra in the main event of UFC 83 on 19 April, 2008, to become the undisputed UFC welterweight champion following a second round TKO (technical knockout) win.

Since then, the Canadian superstar defeated the likes of BJ Penn, Carlos Condit and Nick Diaz, and successfully earned his record ninth title defense by getting past Hendricks in 2013.
