Usain Bolt has insisted his legacy to athletics would survive unscathed even if former relay team mate Nesta Carter is found guilty of doping at the 2008 Beijing Olympics.

Sprint king Bolt achieved a ‘triple-triple’ by anchoring Jamaica to a runaway gold in Friday’s 4x100m final, but was then asked about the possibility of being stripped of one of his medals.

Reports surrounding Carter surfaced in the months leading up to the Rio Games, claiming that in re-tests of frozen blood and urine samples from Beijing, Carter, who ran the 4x100m relay with Bolt, tested positive for a banned substance.
