Thought this was interesting and topical.
In a soccer match between Iran and Denmark, an Iranian player mistook a whistle from the crowd as being the referee's half-time signal, and picked the ball up with his hands in the penalty area. Danish player Morten Wieghorst missed the resultant penalty on purpose, and Denmark lost 1–0.
"The referee gave Denmark a penalty kick, but following consultation with national team coach Morten Olsen, Wieghorst missed the penalty on purpose as a token of fair play, and Denmark lost 1–0. The incident made CNN's "Play of the Day" of 2 February 2003, and Wieghorst received an Olympic Committee fair play award. He was selected the 2003 Danish Player of the Year. He played his last national team game in April 2004, a 1–0 friendly match win against Scotland.
