Swiss soccer player Michel Morganella was expelled from the London Olympics Monday for racist and threatening Twitter statements. After Switzerland\'s 2-1 loss to South Korea Sunday, Morganella used racist remarks to describe his opponents and suggested the South Koreans \"can go burn,\" the Web site 20minutes.ch reported Monday. The 23-year-old immediately apologized, but the head of the Swiss Mission to the Olympics Gian Gilli, already facing criticism for sub-par performances by the Swiss team, sent Morganella home.
