Sergio Perez admits he got a bit of fright when his Force India rolled over during an accident in Hungary on Friday.
The Mexican hit a kerb during Free Practice 1 at the Hungaroring and his rear suspension failed, causing him to crash into a barrier before his car flipped over.
He walked away unharmed but Force India opted not to run his team-mate Nico Hulkenberg during FP2 as they were not sure what caused the suspension failure.
Perez says he was a bit shaken after the crash.
"It was quite a dramatic accident, losing the car at that kind of speed," Perez told F1i.com. "The impact was not that bad, but when I rolled over I was a bit scared. Getting out of the car was quite a challenge, but thanks to God nothing happened. I am here and looking forward to tomorrow.
"We are still trying to find out, but we can see the rear suspension bent out. We are still analysing to make sure we can run for the next day.
"At that point, I didn’t know about the suspension. It was a very strange accident. I was on the Astroturf and suddenly I lost the car. The Astroturf was very dirty at the time but looking at the video I can see the rear suspension just breaks."
The team are yet to confirm their plans for Saturday's FP3, but chief operation officer Otmar Szafnauer is hopeful they can make up lost ground.
"It's been a challenging day as we try to understand the right rear suspension failure on Sergio's car," he said. "The accident cut short our morning and we opted to withdraw from the afternoon session as a precaution until we had a clear understanding of the problem.
"Those investigations remain ongoing and will continue this evening to ensure we can resume running on Saturday. Up until the accident, the morning had looked quite promising for both drivers.
"We had some aero measurement devices fitted to the cars and carried out some work with the medium tyres. Losing the afternoon puts us on the back foot, but I'm optimistic we can recover some of the lost ground tomorrow to be ready for qualifying."
