Usain Bolt no longer has nine Olympic gold medals after the IOC confirmed that relay team-mate Nesta Carter tested positive for the prohibited substance methylhexaneamine.

The decision from the IOC relates to the 2008 Olympics in Beijing where Bolt won gold with the Jamican relay team in the 4x100m.

The disciplinary committee, which comprised of Mr Denis Oswald (Chairman), Mrs Gunilla Lindberg and Dr Ugur Erdener, has ruled that as Carter tested positive the entire team will be disqualified and therefore they will lose their gold medals.

This takes Bolt down to eight gold medals and he loses his record of having won triple gold at the past three Olympics.
