For the past 15 years, Georges St-Pierre has been a key part of Mixed Martial Arts and the UFC. The former welterweight and middleweight champion left the sport in 2013, but returned stronger and better than ever in 2017. Now it appears that Georges is ready to call it quits. He's expected to hold a press conference on Thursday in Canada.

CBS Sports reports Georges has been plagued by health issues, since right after his victory over Michael Bisping at UFC 217 in New York. St-Pierre won the middleweight title, cementing him as one of the greatest fighters the UFC has ever seen.

The legend was plagued by ulcerative colitis and forced to hand over the title.

After spending time away from the ring and changing his diet, he returned to the UFC. He ended up dropping to 155 pounds with the hopes of facing off against Conor McGregor or Khabib Nurmagomedov. However, now both men are suspended and with father time counting down, it appears that Georges will not be returning at all.

Georges willing to return to the ring under certain conditions

Georges previously spoke out about his decision to return and what kind of match it would take to get him back into the Octagon again. St-Pierre said that with relation to coming back to fight, he has more to lose than to win. He is focused on cementing his legacy, which is not a straight path.

He first has to look at what he can gain and what he could lose.

The legend took to his Instagram account to thank his training partner Firas Zahabi. The pair remain undefeated as of today. St-Pierre's upcoming retirement has MMA fighters chiming in, including current UFC welterweight king Tyron Woodley. Woodley praised Georges and even called for a future meeting between the pair, it doesn't even need to be in the octagon.

St-Pierre still has fighters waiting to take on the UFC legend

UFC President Dana White actually had scheduled a fight between Woodley and Georges. However, Woodley did not deliver a strong title defense against Demian Maia at UFC 214, causing White to choose a different opponent for St-Pierre. UFC lightweight champ Khabib Nurmagomedov actually urged St-Pierre to reconsider retirement.

Georges is retiring from the UFC while holding the record for UFC wins in title fights with 13. He also holds the most wins by decision in UFC history and third most title defenses, and along with the most takedowns. ESPN reports that Georges is scheduled to announce his retirement on Thursday in Montreal. A Quebec media outlet first reported his retirement.
