Yuki Tsunoda will start from the pitlane for Formula 1's Emilia Romagna Grand Prix because Red Bull has changed his chassis following his qualifying crash.
The Japanese driver badly damaged his RB21 in a spectacular crash at Imola's second chicane during Q1 – which effectively consigned him to the back of the grid.
The crash was caused by Tsunoda being too aggressive in his first qualifying effort, taking too much kerb on the entry to Turn 5 and losing control after his car bounced back off the ground.
Tsunoda was apologetic afterwards over what he claimed was a silly error.
"Just really stupid from myself, pushing unnecessarily hard," he said.
"We had a lot of changes to the car, pushing that hard without understanding enough about the car…just very unnecessary pushing that hard from that early stage."
As the result of the hefty impact, which included him rolling over the top of the tyre barriers before coming to rest the right way up, the team concluded that his car was damaged beyond immediate repair.
Ahead of the race, Red Bull has elected to make a chassis change, which includes taking parts that are of a different specification.
As this is a breach of F1's parc ferme rules, it means he must start the race from the pitlane.
Beyond the car changes, Red Bull has also taken the opportunity to fit an entirely new power unit.
This includes a new internal combustion engine, turbocharger, MGU-H, MGU-K, battery, control electronics and exhaust. These are all part of his normal allocation for the season.
