Ezekiel Kemboi has been stripped of the bronze medal in the 3000 metre steeplechase after being disqualified for stepping outside the track limits.
The 34-year-old Kenyan was defending his title at Rio 2016, but finished behind compatriot Conseslus Kipruto and Evan Jager of the United States.
Kemboi, a two-time Olympic champion, announced his retirement following the race, but has been denied the opportunity to bow out with a medal following an appeal from the French team.
Mahiedine Mekhissi, who crossed the line in fourth, has subsequently been awarded the bronze, bringing Kemboi's career to a sad end.
The race report on the IAAF's official website read: "A protest was presented by the French team, claiming that Kemboi had stepped outside the track on the curve after clearing the water jump.
"France's Mahiedine Mekhissi, silver medalist at the past two Olympics, was then awarded the bronze medal, having crossed the line in 8:11.52."
