MANILA, Philippines – Former UFC welterweight champion Georges St-Pierre sustained a torn anterior cruciate ligament (ACL) in his left knee while training this week.
St-Pierre, who went on an indefinite hiatus from UFC, plans to undergo surgery to speed up the healing process.
"Just got confirmation that I tore my left knee ACL during training this week. Surgery in a few days and rehab starts right away," the French-Canadian said through his Facebook page.
"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."
According to MMA Fighting, the former UFC champion injured the same knee in mid-2011, forcing him to bail out from his UFC 137 bout against Nick Diaz.
He then suffered a tear in his right ACL months later due to “overcompensation.”
The injuries rendered him out of the UFC for more than a year.
St-Pierre later came back and defeated Diaz and Carlos Condit.
He also successfully defended his UFC title against Johny Hendricks, albeit via a controversial split decision.
He announced his indefinite leave from competitive MMA after the controversial verdict.
