Mark Webber has been given a five-place grid penalty at the Canadian Grand Prix after Red Bull Racing changed the gearbox on his car ahead of the race.
The Australian had qualified on the front row for the Montreal event, but his team discovered a problem with his gearbox in the build-up to the race.
The team elected to change it on Sunday morning, which means he will be moved back five places on the grid.
Webber will therefore now start seventh for the race, with teammate Sebastian Vettel moving up to the front row alongside pole position man Lewis Hamilton.
