Jean-Eric Vergne lost out on his ninth place finish after the race stewards handed him a five-second post-race penalty for colliding with Romain Grosjean.
The Toro Rosso driver attempted to pass Grosjean, but ran into the side of the Lotus as he did, causing minor damage to Grosjean’s front-wing.
Vergne went on to finish tenth, but was promoted to ninth when Pastor Maldonado was also given a five-second penalty for speeding. However Vergne’s penalty now swaps those positions around again.
Grosjean meanwhile finished 11th but felt he lost out on a points finish as a result of the damage from the incident.
“Fighting with JB [Jenson Button] was very very tight but definitely good fun,” said the Frenchman, adding: “It was less amusing with Jean-Eric though, he broke my front wing and he broke my rear floor which made the car pretty difficult to drive afterwards.
“I wasn’t very happy about that as the incident cost me P8. On the plus side, it’s good to be back in the points with Pastor, it’s just a shame not to have been there too.”
