Mark Webber will have a five-place grid penalty for the Belgian Grand Prix because of a gearbox change.
The Red Bull driver, who is Fernando Alonso's closest challenger in the Formula 1 World Championship, finished the last race in Hungary so the gearbox change means he is in breach of the regulations. Webber suffered a similar penalty at the German GP for having a new unit fitted to his car.
A statement issued by the FIA confirmed that the change, which will be made before the start of practice three on Saturday, will lead to a five-place penalty.
"The above driver [Webber] did finish the last race in Budapest and this gearbox change was before the five consecutive events expired," it said.
Webber and teammate Sebastian Vettel have suffered their share of reliability problems this year, although the Australian has not retired from a race.
Speaking about the team's reliability performance this year, Webber said: "Seb lost a lot of points in Valencia. I've lost a lot of points a few times too, so we've had a bit of friendly fire within our own operation, but generally we always grab something at the end. Generally that's down to the quality of the team."
