Germany will lose the Athens Olympics team showjumping gold medal after the International Equestrian Federation (FEI) said it had disqualified Goldfever and rider Ludger Beerbaum for doping.
"The Judicial Committee has agreed that the horse Goldfever and the (rider) must be disqualifed from the event and that all prizes and prize money won at the event must be forfeited," a statement on the FEI website said.
"The FEI will modify the team results at the Olympic Games."
Ointment containing the banned substance Betamethasone, a type of steroid, was used to treat eczema on the horse before the Games. Although independent vets said there would have been no impact on the animal's performance, the FEI has applied the rules of strict liability.
The United States will now take the gold and Sweden the silver with Germany dropping down to third after the horse's results were removed from the record books.
Beerbaum can appeal to the Court of Arbitration for Sport (CAS) within a month.
Germany had already been stripped of their team and Bettina Hoy's individual eventing golds during the Olympics because of a time infringement. Ringwood Cockatoo, Hoy's mount in Athens, also tested positive for the sedative Diphenhydramine during the Games but the FEI said it would make no finding against Hoy.
Waterford Crystal, the showjumper Cian O'Connor rode to win Ireland's only gold medal in Athens, also failed a dope test and the FEI said a date for that hearing would be decided soon.
