Georges St-Pierre was one of UFC's most accomplished fighters before he went on hiatus in December 2017.
The Canadian boasted an impressive record of 26-2 and held the UFC Middleweight Championship before he had to vacate it through injury.
Before his middleweight success, Rush was a three-time Welterweight Champion and was once frequently mentioned as being one of the best fighters in MMA history.
However, injury has stood in his way a number of times. In 2013, he had to vacate his welterweight title and it was three years before he returned to fight Michael Bisping in November 2017.
Just a month after beating Bisping and winning the Middleweight Championship (becoming only the fourth person to have won a UFC title in multiple divisions) St-Pierre had to vacate again.
Despite injury problems, he will still go down as one of the UFC's best fighters - even if he never steps foot inside the octagon again.
And if GSP's latest comments are anything to go by, he won't be too disappointed if he has to make his current hiatus permanent.
That's because he's revealed this week that he actually hates fighting. Yes, one of the greatest MMA fighters of all time actually doesn't enjoy his sport.
“I hate fighting. I really do,” St-Pierre said, per Bloody Elbow. “I know a lot of people don’t believe me, but I’m going to try to explain the best I can."
"In every job, there’s no perfect job that you like everything about it. It’s impossible. My job, as a professional athlete in Mixed Martial Arts, I fight normally - when I was very active - twice a year."
He went on to say that it's those two evenings a year, the fight nights, that he hates the most.
"In 365 days, there are two days that I hate the most: The days that I’m fighting. It’s freaking unbearable.
"The feeling of uncertainty. You don’t know if you’re going to be humiliated, you’re going to be the victor, or you’re going to be the loser. I care so much about it, that it’s freaking unbearable. As much as I try to dismiss it, it’s unbearable.”
It's clear that St-Pierre really did give everything when he stepped into the octagon and that's perhaps why he's been so successful.
But if he does genuinely hate having to fight, then maybe it's best for him to retire sooner rather than later - as he'll still be remembered as one of the very best ever - even if he doesn't make another return.
