Ferrari think it's better to be safe than sorry, so the Scuderia has changed the Internal Combustion Engine on the cars of both Charles Leclerc and Carlos Sainz in Jeddah.
The move – described as a "further precaution" by the Italian outfit – comes after Leclerc suffered two Control Electronics issues in Bahrain.
As a result, Ferrari was forced to add a third CE to the Monegasque's pool of hardware which will equate to a 10-position grid drop for Sunday's Saudia Arabian Grand Prix.
But replacing the ICEs of both its cars after just a single race, even out of prudence, is still a worrying state of affairs for Ferrari.
Ferrari isn't the only team in Saudi Arabia that has undertaken engine changes, with McLaren adding a new Mercedes engine and fresh turbocharger, MGU-H and MGU-K elements to the Briton's PU inventory.
As a reminder, Norris suffered a pneumatic pressure leak in Bahrain that ruined his race at Sakhir.
Finally, Red Bull has also executed changes in the engine department, with Sergio Perez taking on a new Honda energy store and control electronics.
Save for Leclerc, none of the above changes warrant a grid penalty for any of the drivers mentioned.
