The Renault team is confident Romain Grosjean will be able to compete at this weekend's Singapore Grand Prix, despite feeling unwell on Thursday.
Grosjean left the Marina Bay circuit and returned to his hotel to rest, hoping he will be fit to take part in tomorrow's practice sessions. However, test driver Lucas di Grassi has carried out the FIA cockpit extraction test in case he is needed.
The team said that it was optimistic Grosjean will be able to be in the cockpit, but a decision will only be made tomorrow.
