The 28-year-old UFC welterweight champion was in the third round of his third title defense at UFC 100 when the injury occurred.
"I don't remember exactly, but when I was on the bottom, in my guard, and Thiago pushed my knee down and I heard my groin, my abductor snap," said Pierre at the post-fight press conference. "I heard a noise and it was pretty bad."

"(Jackson) says to me, 'I don't care! Hit him with it!'" continued St. Pierre. "So I was like I guess I have to go back there and finish the fight. That's the gameplan."
St. Pierre left the press conference shortly afterwards to be examined by doctors, still in great pain.
