The last time former welterweight champion Georges St-Pierre stepped inside the UFC Octagon was at UFC 167 in November 2013.
After a controversial split decision victory over another former 170-pound champion Johny Hendricks, 'GSP' announced his indefinite hiatus from mixed martial arts competition.
This said decision left the UFC no other choice but to strip him of the title he held for five consecutive years.
Through the succeeding years of interviews, the 34-year old St-Pierre was never really specific about his current status and if a UFC comeback is still a possibility.
But in a recent interview with Joe Buck on "Undeniable", the two-time world champion spoke in further detail about why he opted to walk away from the sport.
"The last two or three fights, I didn't have fun. I did it because I had to, not because I wanted to and I had too much pressure, too much criticism, too much things for too long and it's very hard when you're world champion, all your life is directed (on that)."
"Especially for me with my obsessive-compulsive disorder, I wanted to be the best in the world so everything I do, it's directed on that," he continued. "That's all that mattered for me. I needed to step out of if to have a normal social life. To take a mental break of all that."
For his part, UFC president Dana White already shut down the mere idea of a George St-Pierre comeback. But for St-Pierre himself, the decision still lies with him, and him alone.
"The truth is (the UFC) called me a few times. Sometimes they make the other people call me to have the message," St-Pierre said. "The truth is if I want to be back, it's going to be up to me to tell them when I want to get back."
