Usain Bolt has lost one of his nine Olympic gold medals in a doping case involving Jamaican teammate Nesta Carter.

The IOC said Wednesday that Carter tested positive for methylhexaneamine, a banned stimulant, in re-analysis of samples from the 2008 Beijing Olympics.

Carter and Bolt were teammates on the winning 4x100-metre team, which set a world record of 37.10 seconds. Carter ran the opening leg, and Bolt took the baton third in a team that also included Michael Frater and Asafa Powell.

“The Jamaican team is disqualified,” the IOC said in a statement. “... the corresponding medals, medallist pins and diplomas are withdrawn and shall be returned.”

The relay title in Beijing completed the first of Bolt’s gold medal sweeps in the 100, 200 and relay at three straight Olympics.
