The UFC has gone to Abu Dhabi because it's an access point for fighters who cannot gain entry into the United States due to the COVID-19 pandemic. All shows have taken place without fans as a bubble has been created. Only fighters and staff involved with the event are allowed inside the bubble. Fighters and staff are tested for COVID-19 before they get on an airplane to head to Abu Dhabi. If they test negative, they are then permitted on the aircraft. Once they land in the country, they are tested again and have to quarantine and await the results.
