The Mexican was eliminated on lap 10 of 19 in the Saturday sprint race at the Losail circuit to confirm team-mate Max Verstappen as a three-time world champion.
When Esteban Ocon passed Nico Hulkenberg on the inside, he could not see Perez’s car on the far right, so did not leave the Haas with enough room. This triggered a three-car sandwich that spat Ocon and Perez into the gravel. All drivers were investigated and no further action was taken.
The sidepod and floor of the RB19 appeared to be significantly damaged and were later found to be beyond repair which required Red Bull to make up a second chassis.
Since this chassis build progressed beyond the survival cell stage (containing the fuel tank and cockpit) without FIA supervision, it is deemed to be a third car.
Additionally, this work took place two hours after the chequered flag was shown for the sprint race. Per the FIA sporting regulations, within this time frame all cars “must be covered and ready for FIA seals to be applied in order to ensure that they remain secure until the following day.”
As such, the matter has been referred to the stewards, who have subsequently summoned Red Bull.
Recent precedent points to Perez being forced into a pitlane start for the grand prix and could also have a 10-second penalty added to his race time.
