Nyck de Vries has been unable to complete any simulator work ahead of next weekend’s Singapore Grand Prix.
The Dutchman will be in Singapore as a standby in case Alex Albon has not yet fully recovered from his appendix surgery.
De Vries was trying to get back to Grove to do some simulator running, but due to travel rules since the United Kingdom left the European Union, the 27-year-old could not enter the country using a European ID card.
As a result, he will not have as much preparation as he would have liked for his potential racing duties in Singapore.
The 2021 Formula E champion deputised for the Thai-Briton when he came down with appendicitis last time out in Monza, and he finished a brilliant ninth on his debut.
Following surgery, Albon suffered respiratory failure that saw him taken into intensive care, but he recovered overnight, and was sent back home to recuperate.
The aim for him and for Williams is to be ready for the Singapore Grand Prix, but in case he has not fully recovered yet, de Vries will be waiting in the wings.
The 61-lap race at the Marina Bay Street Circuit is one of the most demanding on the calendar, making it difficult for a driver that is not back to full fitness following major surgery.
In a recent social media video, Albon revealed that he had begun to walk under his own steam, and was doing all he could to prepare for the next race.
“I feel pretty good, I feel okay,” he explained.
“Obviously on Saturday I had a slight issue and the doctors did an amazing job, and I’m very grateful that they got me in good health and out of the hospital by Tuesday.
“I’ve been in Monaco since then, I’ve been starting to walk around. The goal is to be ready by Singapore, which is going to be tough; it’s one of the toughest races that we go to, so not an easy one, but let’s aim high and see what happens.
“And just a quick message to say thank you for all the kind messages,” he added. “I’ve been reading them all – or as many as I can, and it means a lot. Thanks, hopefully see you in Singapore and peace out.”
Albon is locked into a multi-year contract with the Williams team, while Nicholas Latifi is currently out of contract at the end of the season.
Following de Vries’ exceptional display at the Italian Grand Prix, he is being linked with the Canadian’s seat.
