Cape Town - Romain Grosjean faces a five-place grid penalty following a gearbox change in the wake of final practice at Monza.
The Frenchman was on his fourth lap of FP3 when a mistake left him stranded in the gravel.
Grosjean hit the inside kerb at Ascari, which pitched his VF16 into a spin and into the gravel.
The Haas team later announced that Grosjean's VF16 required a new gearbox, which they fitted in the break between FP3 and qualifying.
As a result he faces an automatic five-place grid penalty.
