Usain Bolt

A decision by the Court of Arbitration for Sport here has robbed retired Jamaican sprinter Usain Bolt of his perfect record in the 4×100m relay. The CAS on Thursday dismissed Bolt's teammate Nesta Carter's appeal against disqualification from the 2008 Beijing Olympics for a positive doping test leading Bolt to lose his ninth gold medal, the Sun reported. In a statement released by the CAS panel for the discoveries made eight years later, the sport body said: "Could not accept any of the arguments raised by Carter contending that the test results should be ignored or the IOC (disciplinary) decision should otherwise be overturned for certain alleged failures".
