Force India reserve driver Nicholas Latifi won't be running with the Silverstone-based outfit this week for health reasons.
The 22-year-old Canadian was scheduled to test on Thursday, this week's final day of running in Barcelona.
After informing the team of his condition last week, he took to Twitter to explain the issue to his followers:
"Disappointed I can't be at the Force India launch in Barcelona this morning," he wrote.
"A serious infection put me in hospital last week and I'm now recovering at home. Aiming to be back on track in the next four weeks. Have to say, the VJM11 looks fantastic!"
Force India has yet to decide who it will run on Thursday. Development driver Nikita Mazepin will be handling testing duties today.
