Usain Bolt has lost his triple triple gold record after the International Olympic Committee confirmed that Jamaica would be stripped of their mens 4x100m relay medal from the 2008 Olympics Games in Beijing.
Carter and Bolt were teammates on the winning 4x100-meter relay team, which also included Michael Frater and Asafa Powell.
A statement from the International Olympic Committee said re-analysis of team member Nesta Carter's Beijing sample had tested positive for the prohibited substance methylhexaneamine.
"The Jamaican team is disqualified," the IOC said in a statement. "... the corresponding medals, medalist pins and diplomas are withdrawn and shall be returned."
The relay title in Beijing completed the first of Bolt's three gold medal sweeps in the 100, 200 and relay at three straight Olympics.
The decision to strip Jamaica of their 4x100m title deprives Bolt of one of his nine golds, won across three Games between 2008 and 2016.
