Sergio Perez is set to return for Racing Point at the 70th Anniversary Grand Prix after he missed last weekend's race following a positive coronavirus test.
The Mexican driver has been in quarantine for seven days after he returned the positive result ahead of the British Grand Prix last Wednesday.
But Perez has been given the green light to race at Silverstone by the local medical authority providing he returns a negative Covid-19 test. Nico Hulkenberg is on standby if Perez is not fit.
A statement from Racing Point read: "Public Health England have confirmed that Sergio Perez's period of quarantine has been completed.
"In line with the FIA Code Of Conduct, Sergio requires a verified negative test result for Covid-19 before he can enter the paddock. The testing process is taking place today.
"The team expects to make a decision on who is driving alongside Lance [Stroll] later today or first thing tomorrow morning."
There had been some doubt over whether Perez, who became the first Formula One driver to go down with coronavirus, would be available to drive after the period of quarantine for those testing positive extended to 10 days.
But Perez's Racing Point team are using the date of his first inconclusive test, which took place last Wednesday 24 hours before the change from seven to 10 days was enforced.
Earlier this week, Perez reported that he was free of symptoms. Hulkenberg, Perez's replacement for the British Grand Prix, qualified 13th at Silverstone last week, but failed to start the race following a technical failure.
