Georges St-Pierre said he "cried" when the decision was finally made for him to withdraw from next weekend's UFC 137 main event. In an exclusive interview with Sportsnet on Wednesday, the UFC welterweight champion said that he wanted to keep training and hopefully fight through an MCL injury he suffered on Saturday -- which he called a moderate ligament strain. But while training on Tuesday he hurt the hamstring on his other side while compensating for the original injury. And that's when he knew he wasn't going to be 100 per cent for the fight on Oct. 29 in Las Vegas. Ultimately he agreed with his manager and doctors that the best decision for him was to pull out.
