Sergio Perez completed no running in Friday practice for the Brazilian Grand Prix after an accident for reserve driver Dani Juncadella in FP1.

Juncadella was driving Perez's car in the opening session at Interlagos, but hit the barrier at Turn 8 having got wide on to the kerb on entry. The crash caused a red flag and with the Force India seeing a lot of heat soak the team changed hydraulic components which ruled Perez out of the season session. Perez himself said it was just unfortunate and hopes FP3 will allow him enough running to recover.

"It's disappointing not to run today and what happened with Daniel is bad luck," Perez said. "This is how things are in Formula One and sometimes you just have to accept that it's not going to be your day. Final practice will be even more important now but hopefully I can get up-to-speed before qualifying."

Team principal Vijay Mallya said the problem was compounded by a disjointed FP2 preventing the team from gathering too much information on how the car will behave.

"It was quite a testing day on Checo's side of the garage," Mallya said. "Daniel drove the car this morning, but made a mistake coming through turn seven and ended up in the barrier. It was not a heavy impact, but the car experienced a lot of heat soak, which damaged some engine hydraulic components.

"The decision was taken to replace them as a precaution, which unfortunately deprived Checo of running today. With only one car available this afternoon, we adjusted our run plan to ensure we gathered all the data we needed prior to the race, although with several red flags during the session it was not easy to complete a long run without disruption."
