Usain Bolt is no longer a nine times Olympic champion after being stripped of his 2008 4x100m relay gold because his Jamaica teammate, Nesta Carter, has been found guilty of a doping infringement.
It means Bolt can no longer claim to have done the "triple-treble" - gold in the 100m, 200m and 4x100m relay in 2008, 2012 and 2016.
Re-analysis of Carter's samples from Beijing 2008 have led to a positive test for the prohibited substance, methylhexaneamine,  according to the international Olympic committee, and he has been disqualified from the 4x100m relay event.
