The status of next week’s scheduled UFC event in London remains uncertain after US president Donald Trump announced on Saturday that he was extending his country’s temporary travel ban imposed on mainland Europe to both Ireland and the United Kingdom.

The restrictions, where were announced earlier this week, are designed to help limit the spread of COVID-19 within the continental United States and presents obvious challenges to next weekend’s card in the English capital. The UK now has around 1,140 confirmed cases of the virus within their borders.

The restriction places obvious challenges on America-based fighters and UFC staff alike, although US citizens and green card holders will not be refused entry back into the county. However, some reports suggest that people re-entering the US may be required to enter into isolation for a period of time. It takes effect from midnight on Monday.

UFC brass have remained insistent that the London card will go ahead as planned, but that announcement was made prior to the vast majority of UK sporting bodies voluntarily halting operations. Dana White commented this week on the matter, saying that he had consulted with Trump and vice president Mike Pence, along with doctors, as they proceed with planned events.

They announced this week that Saturday’s card in Brasilia will take place behind closed doors, while another event originally set to take place in Ohio will now happen at the UFC Apex in Las Vegas.

The London card is set to be headlined by Leon Edwards vs. Tyron Woodley. Per reports, Woodley has already left the US on a flight.
