Any chance of UFC superstar Georges St.Pierre returning to the Octagon in 2014 would now appear to be over after the Canadian revealed today that he has torn his left ACL in training, meaning he faces another lengthy spell on the sidelines.

“Just got confirmation that I tore my left knee ACL during training this week,” GSP revealed on his Facebook page.  “Surgery in a few days and rehab starts right away. We all face challenges in our lives and I know only one way to take this one: Pain, hard work, no shortcuts and I will soon be back at 100%. Stay tuned and thanks for your amazing support, as always.”

St.Pierre has been down this road before, having torn his right ACL in 2011 which left him out of action for almost a year.

It should be stressed that there was no indication that St.Pierre was going to return this year anyway after announcing just a few months ago that he was taking an extended break from the sport.

However, this injury ensures that there’s no chance we’ll be seeing him return in the near future, and given the serious nature of the injury it leaves a big question mark as to whether the 32 year-old will want to compete again, and whether he will still be the same fighter if he does.
