The 2016 Summer Olympic Games are coming to Rio De Janeiro, but the equestrian events of next year’s games might have to take place outside of Brazil, according to the Brazilian Equestrian Federation.

Federation President Luiz Roberto Giugni issued the warning last Wednesday at a news conference in Sao Paulo, following delays by The Brazilian Agriculture Ministry in issuing the documentation needed to allow horses from Europe, the United States, and Canada to enter and leave the country, according to The Associated Press.

“If the problem is not resolved by the end of the month, we run the risk of not having the event in Brazil,” Guigni said, “We are running late.”

This would not be the first Olympic Games to require the equestrian events to take place outside of the host country. According to the AP, biosecurity regulations required the equestrian events for the 1956 Melbourne Olympics to take place in Sweden, and the 2008 Beijing equestrian events to take place in Hong Kong.

A statement issued by Ingmar De Vos, president of The Federation Equestre Internationale(FEI), the international governing body of equestrian sport, did confirm that “the process of approval of the equine health certificate by the Brazilian Ministry of Agriculture has already taken a lot of time and is still not finalized,” but also emphasized confidence that a solution is in the near future.

“We have had further discussions earlier this week and I expect the Ministry of Agriculture to issue this certificate very soon so that we can carry on with preparations for the Olympic Games,” said de Vos, “We are confident that our horses will be allowed to travel back and forth to Rio to participate in the 2016 Olympic Games together with all the other Olympic sports. We are looking forward to very successful Olympic equestrian events at Deodoro [equestrian center] next year.”
