Sergio Perez is set to start the Qatar Grand Prix from the pit lane and with a 10-second penalty after undergoing extensive repairs to his Red Bull under parc fermé conditions.
The Mexican was set to start 13th after a difficult qualifying session on Friday at the Lusail International Circuit, though he had found improved performance in the Sprint Shootout to reach SQ3.
But whilst battling for points alongside Haas' Nico Hulkenberg and Alpine's Esteban Ocon, the trio collided and left Perez and the Frenchman in the gravel - the Red Bull extensively damaged.
In their attempts to repair the RB19 ready for the race proper, Red Bull mirrored a Willaims transgression from Suzuka where the team built up too much of Logan Sargeant's car after it was deemed a new chassis was needed following a qualifying crash.
A report from the FIA Technical Delegate read: "Last night the Oracle Red Bull Racing team worked on car number 11, chassis 02, two hours after the chequered flag of the Sprint.
"Chassis 01 got damaged beyond repair during the accident in the Sprint.
"Chassis 01 and all other components fitted to it at the time of the Sprint were covered on time at 23:08, two hours after the chequered flag was shown at the end of the Sprint.
"As chassis 02 was assembled without supervision to more than an assembly comprising a survival cell as defined in SR Article 27.2, this has to be considered as a third car available to the competitor."
Sargeant was found to have breached parc fermé regulations in Japan and was handed a pit lane start alongside a 10-second penalty.
Red Bull has also fitted an entirely new power unit to Perez's car, with each of the components surpassing the limited number as allowed within the Sporting Regulations.
