Massa withdrew from the Hungarian Grand Prix after ending final practice early because he felt unwell. It came after he felt sick and dizzy during Friday running.

The team's reserve driver Paul di Resta replaced him for qualifying and the race, retiring from 18th with 10 laps to go because of an oil leak.

Massa was set to complete a full-day of testing on Tuesday at the Hungaroring but has returned home to recuperate ahead of a planned return at Spa next month.

As a result, Williams has drafted in Stroll to cover his duties, while Formula 2 driver Luca Ghiotto will take over on Wednesday.

The Hungary test will mark 22-year-old Ghiotto's first time driving an F1 car.
