Mark Webber's chances of winning at Spa have been dealt a blow with news that he has incurred a gearbox change penalty.
Webber, who arrived at the Belgian track second in the Drivers' Championship, was one of the few front runners who put some mileage on their car on Friday.
The Red Bull racer completed 13 laps in FP1 - where he was fifth quickest in the wet - before sitting out the rain-soaked second session.
However, later that night it emerged that Webber's RB8 needs a new gearbox.
His team made the change overnight meaning Webber has incurred an automatic five-place grid penalty.
