'The best ever': MMA community salutes icon Georges St-Pierre ahead of impending retirement

The mixed martial arts world is reacting to the impending retirement of legendary UFC fighter Georges St-PIerre, who reports suggest will announce that he is stepping away from the sport on Thursday.

While a formal statement from St-Pierre won't arrive until Thursday's press conference, a host of well-known names within MMA have sounded their appreciation for a fighter who will walk away from the sport with far more friends than foes, including one of the sports most famous faces.

Per reports, the failure to arrange a match-up with Khabib Nurmagomedov appears to be the impetus for St-Pierre, 37, making the decision to cut short a combat career which saw him win world titles in two separate weight divisions.

His influence on the sport will endure long after he is gone, however. The standard-bearer, perhaps indefinitely, for what it takes to succeed in a sports as ferocious as MMA, St-Pierre has been heralded for his achievements by all corners of the sport.

In addition, the latest post of St-Pierre's Twitter profile from Tuesday appears to foreshadow the news of his retirement, as it shows him with longtime coach Firas Zahabi along with the text: "We remain undefeated together."

However, the news hasn't gone down so well with some members of the UFC roster who are frustrated with Nurmagomedov openly chasing bouts outside of the division in which he is the champion. 

Nurmagomedov will almost certainly compete just once this year and, with the list of contenders continuing to expand at the summit of the UFC's 155lb division, two fighters in particular have reacted negatively to the implications of the Russian's perceived reluctance to defend his title - former Khabib opponent Al Iaquinta and one of the current top contenders Dustin Poirier.
