Brazilian GP: Perez to miss FP2 after Juncadella crash in FP1

Juncadella replaced Perez for FP1 at Interlagos, but he crashed heavily at Turn 8 and stopped the session.

Perez will skip this afternoon's second session while Force India investigates a heat-soak issue with the car's engine that resulted from the shunt.

Mercedes DTM racer Juncadella described the incident as the "weirdest" crash of his career.

"It's really a shame when you end the session like this, especially on a race weekend because the main thing is that Checo has his car ready," Juncadella said.

"It was the weirdest crash I've ever had, because it was really unexpected.

"The track was weird to manage, with the new asphalt there was only one line and it was getting better every lap. But on that lap I just went a bit wider on the kerb.

"I thought I could use it, but I was way too optimistic and from there you have the wall in front and if you have a moment and don't catch it, it just goes straight into the wall.

"I tried to crash as straight as possible, but when you crash in such a small place with not a lot of room to go off it's hard."

Juncadella, who visited the circuit medical centre for a precautionary check-up, said the crash was unlikely to affect his slim chances of graduating to an F1 race seat next season.

"It has an impact mentally - confidence-wise it's not the best - but you don't take a decision from one crash," added the Spaniard, who has an option to remain in the DTM next season.

"Obviously it's not the best way to finish it.

"It's hard. We see less teams, some of them signing a lot of drivers - there's a lot going on. It's still early to make a decision."
