Nico Rosberg will take a five-place grid penalty for the Belgian Grand Prix after requiring a gearbox change.
The Mercedes driver suffered a failure during final practice at Spa. Rosberg only managed five laps on Saturday morning before his car ground to a halt at Pouhon.
Given Friday's rain, Rosberg will go into qualifying with very little dry running in addition to the handicap of his penalty.
Red Bull's Mark Webber is also carrying a gearbox penalty for Spa qualifying.
