Pedro de la Rosa will get a grid penalty for the Singapore Grand Prix following a gearbox change before final practice.
The HRT driver finished the Italian GP in 18th place but the team discovered a problem with his gearbox after the event.
The change at the Marina Bay circuit will result in him getting a five-place grid drop, which will almost certainly drop him to the back of the starting order.
HRT has introduced a new floor for this weekend's race, its first significant upgrade since May.
