Triple Olympic gold medalist Stephanie Rice says she has undergone successful surgery on her right shoulder to repair a long-term injury which threatened her buildup to the 2012 London Olympics. Rice told followers on the social networking site Twitter Wednesday that the surgery in Melbourne was apparently successful. 'Just got out of surgery. Things went well, thank you God,' Rice tweeted. Rice opted for surgery while representing Australia at last month's Pan Pacific championships in Irvine, California, taking a decision which ruled her out of October's Commonwealth Games in New Delhi.
