Bolt loses 2008 Olympic relay gold in teammate's doping case

GENEVA (AP) — Usain Bolt has lost one of his nine Olympic gold medals because of a doping case involving Jamaican teammate Nesta Carter.

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

Olympic rules state the entire relay team can be disqualified and stripped of medals if one runner fails a doping test.

Carter and Bolt were teammates on the winning 4x100-meter 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. "... [T]he corresponding medals, medalist pins and diplomas are withdrawn and shall be returned."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.

Bolt set world record times for all three sprint titles at the Bird's Nest, establishing himself as the defining superstar of Olympic track.
