The prestigious Dubai World Cup meeting is the latest major event to be cancelled over the coronavirus pandemic. Even that plan became untenable as the threat of spreading COVID-19 grew.
The higher organising committee of the Dubai World Cup, one of the world's richest horse races, has made a decision to postpone the 25th edition of the global event to the next year in light of the novel coronavirus Covid-19 outbreak.
Organizers earlier had announced they would run the races without fans in attendance.
Sheik Mohammed Bin Rashid Al Maktoum is both ruler of Dubai and the driving force behind the country's racing program as head of Godolphin.
Globetrotting dual Melbourne Cup placegetter Prince of Arran is stranded in Dubai following the cancellation of Saturday's World Cup meeting. He was favourite for the World Cup having run so well in Saudi Arabia. Casse had not yet left the United States.
Fellowes told the Racing Post getting Prince Of Arran back to England was going to be hard in the wake of travel restrictions around the world. "It is unprecedented in the impact it is having on our game and the wider community, and as a community and as a code, we all need to take the unprecedented and required actions to get through this together".
