Adam Gilchrist once walked despite not being given out in World Cup semi-final

Ex-Australia wicketkeeper-batter Adam Gilchrist walked despite not being given out in 2003 World Cup semi-final against Sri Lanka. Gilchrist swept an Aravinda de Silva delivery and got an edge, which bounced off from his pads to Kumar Sangakkara. "To see...umpire shaking his head, meaning, 'Not out', gave me the strangest feeling," Gilchrist wrote in his book describing his dismissal.
