Bruno Senna has been given a five-place grid penalty for the Singapore Grand Prix after his Williams team changed his gearbox ahead of Sunday's race.
The Brazilian, who damaged the gearbox when he hit a wall in qualifying on Saturday, will now start 22nd on the grid for the 14th race of the Formula One season.
Senna's team-mate, Pastor Maldonado, will start second on the grid alongside McLaren's Lewis Hamilton.
