Hulkenberg was hit by Valtteri Bottas, causing his race to end early and Bottas' race to be severely compromised.
"We were obviously three in one corner, Seb on my outside, I was in the middle, Valtteri on the inside," he said. "But the way I saw it is Seb didn't give me much room, he really turned in on me."
"I couldn't pull out as I also had a car on the inside."
