Sergio Perez has landed a seven-place grid penalty for the Brazilian GP after his first-lap collision with Kimi Raikkonen and Adrian Sutil in Austin.
The incident spelled the end of the race for both Sutil and Perez, who also gets two penalty points.
The stewards noted: "The driver of car 11 could not reasonably have expected to complete the maneuver. His collision with car 99 was reckless."
Perez said: "What happened today is really unfortunate. I made a move on Adrian at Turn 15 when he left the door open, so I went up the inside. Then Adrian started to close the door and I had to try and brake later than him.
"By doing so I was unable to avoid contact with Kimi, which caused me to make contact with Adrian also. I just didn't expect Kimi to be in that position. It's a big shame because I had a great chance to keep up my run of points finishes and I was determined to do well in such an important race."
